Splitting Modify Ticket Rights

We have a development and a QA department. What I’d like to do is let the
developers post their comments when fixing bugs, and log their time etc.,
but i only want the QA people to have permission to actually mark it as
resolved (once they’ve confirmed the fix). Is there a way I can split the
Modify Ticket rights up?
