bewares videos

Ive been building a supernova setup for my ddr machine using a minimaid adaptor. I want to try and have all ddr songs and there official background videos. my question is, is there a way to get the bewares extreme background videos to play only on the songs they should. By putting them in the random movies folder they should work with the scripted 8th mix songs but i dont want other songs using them randomly. Maybe like a extreme vids folder inside random movies? I dont know my brain is fried from trying to figure this out.
