Of course you can
Way back, when stacks were first introduced, I was extremely interested in them, and their inner workings, as I had wanted stacks for my image library for years. You can read the results of my detective work in
this thread, where I answered a similar question, in reverse, to your own. At the end of my last post in that thread, there is a link to another thread, where I have typed some more stuff about stacks that you might find useful.
If that leaves anything unanswered, just ask.
