Raplace track number by incremental letter

Hello everyone, does anyone know how to change the track number with letters?
eg

01 - Artist - Track name
become
A - Artist - Track name

And what if an album has more than 26 tracks?

I've a few albums with more then 2 tracks, but in this case I use this method:

A
B
c
...
...
...
X
Y
Z
Za
Zb
Zc
etc

any help? :book:

You can use "Convert > filename - filename" and enter
old filename:
%1 - %2 - %3
new filename:
$char($add($num(%1,1),64)) - %2 - %3
