Is it possible to have something similar in MC 23?
Yes. In fact, I would think you could create something exactly the same, if that was the best solution for you.
As I understand it, you have multiple drives, each with the same directory structure or a directory structure based on the same rules, which is based on some attributes of the music. I don't understand from your image what attributes you are using for the structuring, but if you do, and can write the rules down for it, then someone will be able to help you create what you want.
i.e. You have some structure like;
"D:\Attribute01\Attribute02\Album\Track"
and that is repeated on various drives;
"E:\Attribute01\Attribute02\Album\Track"
"G:\Attribute01\Attribute02\Album\Track"
"W:\Attribute01\Attribute02\Album\Track"
Within MC, all you would need to do to recreate what you are using now is a create a View that looks at the path to the files, ignores the drive letter, and groups all your music by the Attributes you want. MC has a comprehensive Expression Language that could do that, and there a quite a few good Expression Language experts around here who could help you define the correct Expression. I'm not really one of them though.
Something like;
removeleft([filename (path)], 3)
would be close though, to select the file and group them across drives. Yep, that simple. Because now MC would just select the audio to display based on the "Attribute01\Attribute02\Album\Track" component of the location on disk. I just built such a View, and it worked fine for my data. But I don't have your multiple drive setup, nor do I know what attributes you want to group audio within. So my simple example just selected all the files based on the Expression above, and then Grouped them by [Album] and sorted within [Album] by [Track #], which is the default but is customisable.
If you then wanted to Group and Sort using the Attributes buried in the directory structure and file name, there would be quite a bit more work, but not impossible.
A better solution is to take those Attributes that you are using and get them into Tags in the MC Library. MC then wouldn't care where the files are located, on which drive. It would just display the files by the Attributes stored in tags for each file. Each of your Attributes would probably map to existing Tags in MC, and if not, new Custom Tags can be created. MC will still be able to manage the directory and file structure as you want into the future when you add new files. It has a great tool for doing that. MC also has tools to read your existing directory structure and file name, using a Template you define based on your rules, and update Tags in the library from that information. So you won't have to manually key in all the Tags for your collection.
You may need help with deciding how to move forward. You need to provide more information so that people can help. Specifically, your structuring rules. You will also need to help yourself by learning about Creating and Customising Views, Tagging and Custom Tags, the Expression Language (although as above, if you can define what you want to do, usually people here will help you with Expressions), the "Fill Properties from Filename" function, the "Rename, Move, & Copy Files" function, and so on.
Back to you.
