[FE6] Raise Roy's level cap and Roy's only

Hello everyone. I am new to romhacking and currently using FEBuilder for my little project. I know there is a patch built in to raise level cap for everyone but can I make it specific to Roy only?

Skillsystem in FE8 has that function. So you could probably theoretically port that over to FE6 after you figured out the diffrences in code between the games. Otherwise, you are probably out of luck big time.
