Managing access for Grade Step Progression processing

Summary

How do you manage access for Grade Step Progression processing?

Content

We have multiple sites within our company and currently there are only 2 sites that use grade ladders.  We don't want to give those sites overall 'comp mgr' or 'comp admin' to process grade progression changes.  How would you manage this so they they can process their own site?  Through custom security role?
