Movie Subsets

Hi I am trying to organise my movies so that the sets have a sub set, I will use Disney for example, in the main page each set is shown so I would like to decrease my library on the first page to look like Disney Animated and then inside the disney animated tab say Toy Story then followed by the individual files, is there a way to do this, I have tried editing the .nfo file using <set>Disney Animated</set> <set>Toy Story</set> and <set>Disney Animated</set> <subset>Disney Animated</subset>

I hope that makes sense

Many Thanks

just thought, it would be similar to the tv design, tv show then season only for movies
