Coming later this week in TRIBUTE, we've opened up MyGM mode for you so you can now fully replace shows and edit things to your hearts content!
Replace managers with any wrestlers or mods you like, with ability to edit their names, renders, etc, as they appear in MyGM
Edit/replace brand data
Replace titles/belts with any other title you want
Change the arena IDs, to load whatever arenas you want
Full edit the logistics data, so you can edit things like unlock price, asset requirements and more
Edit the wrestler data for the mode (you could already do this with Tribute)
