I was told that I could use scripts for what I need. However, I wouldn't know how to create such a script as I am not a programmer. So far, I haven't found one suited to my needs, but I am hoping one already exists, or perhaps somebody could help me in the creation of one. Basically, what I need to do would be to alter numbers in titles in an incremental manner (but not the simple kind).
For example, for the before and after :
personal edit 1 - final 1 into personal edit 01 - final 01
personal edit 1 - final 2 into personal edit 01 - final 02
personal edit 2 - final 1 into personal edit 02 - final 01
personal edit 2 - final 2 into personal edit 02 - final 02
And also, if need be:
personal edit 1 - final 1 into document 01 - final 01
