I did a search and I couldn't find anything so here's what I need to find out...

Is there anyway to give each costume ingame its own name?

i.e - I have the grey fox textures on meta knight along with power ranger textuers in his other costume slots.. Is it possible to say, have the first costume say Grey Fox with a Grey Fox CSP and if I change costumes in the selection screen to his power ranger texture, for it to have changed from Grey Fox to Power Ranger?

I edited it and it says Grey Fox just fine now, but I just want alternate names for each costume
