save as or pack and go or other ?

I have assembly and I'd like to have new assembly with different name lets say ca5 to ca3 with all parts in nwe assembly autonatically renamed to ca3 with drawings

pack and go will only copy files with drawings but I can not really rename files but add suffix or prefix

I did try save as starting with drawing but I could change ONLY drawing name and all other were old names is there any way to copy parts with ALL NEW NAMES?
