Hello! I Want to change AutoMule names!

Hi I’m using blizzhackers-kolbot.

everything is perfect, but I want to change my AutoMule account, char names.

If the account was “automule1, automule2, automule3… … …”

I want to change it as “automule_A, automule_B, automule_C… … …” like this way.

And the Char names are now “automuleba, automulebb, automulebc… … …”

But I want to change it as " automule_A, automule_B, automule_C… … …"

where should I look in to?

Have a nice day~:D
