I downloaded the Spear Pillar stage textures for Pokemon Black and White, with Zekrom, Reshiram, and Victini. The filenames had these short little tags like "STGXXXXXX_1" and "STGXXXXXX_2" and "STGXXXXXX_3"

When I pick Spear Pillar as my stage, it gives me a random one of these. Now, I want to do the same with LenSho's Embedded Tower for Jungle Japes. How do I make it do the random stage select? There are six I want it to pick from....if that's impossible, three also works.
