You can do that now. Set up auto import to watch different folders according to media type. Then edit each one to include the types you want.
What about different folders with the same media type? All I see is a "Get Movie/TV Info" checkbox, which is either enabled globally across the entire auto-import list, or not at all. I have several video folders, some I would like to auto-update with information, others I most definitely would not.
It should not fill any tags that have information.
It would be better if I could specify which (if any) tags I want updating at all. For instance, I have everything organised using Keywords. It's a mainstay view for videos, and I use the fact that I can have a list seperated by ';' and '\' to allow me to drill-down into various categories.
When I ran auto-import last night, it generated a vast number of these keywords for things I haven't gotten around to categorising yet (which would normally then appear in 'Unassigned', which is fine), and it made a real mess of the view.
I would like it to leave Keywords
always alone, and never ever ever attempt to update that tag from the Internet. Not ever. If there's some data it wants to give me, that's fine, but please let me specify where it should go.
