Tool or script to rename all the drawings of rigg on one frame

While rigging a multi view characters, i like to use a naming convention for all the drawings of the quarter front view to use the QF prefix. But its a pain the rename all the of the drawings one by one. Is there a way to do it faster for the whole rigg?

Thank you!

I do not know if this is what you are looking for, but StylusRumble has a YouTube video about a Find & Replace script.

That script is here:
