It's been a little while and there are no replies. Bad question? Unclear question? Does no one know? Is this in the wrong part of the site? Is this forum dead? Something else?

Good morning, Only recently started messing with GBA roms, specifically FireRed. I'm trying to piece together a hack for personal enjoyment, and one of the things I want to do is add re-match teams to trainers which don't have them. I know how to create new trainers and how to edit extant trainers. I haven't learning decomp yet, I'm still using tools like AdvanceMap and a trainer editor, but using those tools, I can insert new trainers and they work (and some basic scripts). I don't know how to associate trainer-data with a trainer as a rematch team. So, that's my question: How do I add rematch teams to extant trainers such that the Vs Seeker will proc them appropriately? [mods, if this is in the wrong section, please move it]

If you can solve this, I'll be forever in your debt. How does one add rematch teams to extant trainers for VS Seeker rematches in FireRed/LeafGreen that will activate with the other rematch teams?
