[SUGGESTION] "Reassign gear/ability mats" option

I really want something like this. Just last night I came up with an idea for a team that I think would be very good, maybe good enough to beat reven. Problem is, I have one of the necessary characters geared a little too high. So if this team does end up being good or even decent, it sucks that I simply can't use it since there's no way to degear a unit.
