Reset emblem for 5* heroes

Hi there
It occurred to me it would be cool to have a way to get back your AM in the case when you max a 5* hero but later regret it.
Something similar to the reset emblem for class emblems.
At least getting back the 4* AM (scopes, tabards…maybe blades and tomes…)
For example, I maxed Kunchen recently, I did that out of excitement of getting him…but now I realize he‘s not really fitting my gameplay and mostly seats on my bench.
I‘d love to get a way to rollback this move and give the tabards to someone else…
