I saw some answers to similar question here, but either it doesn't match my needs or I did not understand them.

Long story short: I didn't change rigify type on the fingers to super_finger but I already did the weight repaint job and generated the rig. Do I have to redo the whole thing? Is this losted hours of work?

full story: My problem is I have an already generated metarig. I did aaaaall the weight paint corrections (there was a lot because I added few custom bones to the original armature, like a bag, some swords etc) But when I started animating, I noticed there was no controls for the fingers (you know, the lines you select and scale to retract fingers) I found out on stackexchange that I should change the rigify type on those fingers to super_finger instead of tentacles. Do I have to regenerated the whole thing and redo the whole weight repaint job again?

Thank you
