UNREAL 4 - Morph target that triggers after figure receives X number of pickups, like coins?

Hi, does some one knows a good video tutorial or can show a BP image to follow for this type of issue:

I have 4 transformations for a single figure (A), each transformation happens when main character (B) collects and drops pickups to this figure (A), then after figure (A) gets X number of coins or pickups Morph target gets activated, i haven´t found any type of tutorial for this anywhere…

Please help
