Assigning GL accounts to Payroll Pay Types

I cannot figure out where to edit the GL accounts that are assigned to certain pay types. I have searched up and down and through several forums and am so lost on what to do. For example, currently our pay type 9-Misc hits whatever GL account the employee's regular pay hits based on his position. If I wanted to add a bonuses GL to separate the expenses, how/where do I change the GL in pay type 9?

Thanks!
