Ability to update incorrect champ in AQ

Hons24

I recently entered AQ raids with the incorrect champ. I needed bring an Assault champ and mistakenly brought a tactician champ. I contacted support and they don't have the ability to revert this. I entered and didn't move.
I can't be the only one that has ever done this and support needs the ability to correct given the 180 raid tickets i have to spend to get in. Note, it was my mistake and i own that, but there should be a way to correct it.
