Hi at all!  
I'm using mp3tag to tag my flacs. Until now everything worked fine and I could solve most of my problems/wishes by trying or searching.

But now, I think I've reached my limits (for the moment):

I have an audio book and chapters are between 8-13 single files. Of course I can distinguish them by adding the tracknumber, but I'd like to add individual numbering for each single chapter.

Right now if only considering the title column, I have this

Chapter A  
Chapter A  
Chapter A  
Chapter A  
Chapter A  
Chapter B  
Chapter B  
Chapter B  
Chapter B  
Chapter B  
Chapter B

It should look like this:

Chapter A (01)  
Chapter A (02)  
...  
Chapter A (11)  
Chapter B (01)  
Chapter B (02)  
...  
Chapter B (13)  
...  
Chapter Z (10)

Is there any possibilty to do this with a function?

Would be great if anyone can explain what is possible or what a possible workaround could look like.

Thanks!
