Feature Request: Custom Username instead of "bl_num"

[timmy-time]

I've read through the closed, already existing request for custom usernames, and I understand that there's no way in knowing what the user's password is, hence matching the passwords is unfeasible.

What I am requesting, is a variable that can be set during Product Purchase, to specify a new, or already existing username that's on the Pterodactyl Panel. I've recently migrated my billing panel to Blesta, and I would love if this is something that can be added.

From the code I've read, it seems easy enough, but I don't have the expertise or experience in creating Blesta Modules for me to successfully modify it myself.
