So here is actually how you get around this:
Program your given skin to filter results so that they only can be sourced from a given folder.
So as far as the program knows you just have 2 links on your home screen both going to the tv shows. However everything in each one is coded by the skin to filter out results not from their defined directory. This would visual accomplish the results while still keeping all the data in the same database.
So if you search something for example the program would actually search everything and then filter out what is not in the directory you actually care about. So while every action would take up lets say twice as much memory and cpu as required at least it would work.
