How to setup a rule to skip the cost center manager and go to the next job level if expense report owner is cost center manager?

Content (required):

I am trying to setup an approval rule based on cost center managers and job levels. The goal is to get the cost center manager, unless the user who is submitting the report is also a CC manager - in this case he approves his own expense report. I want the rule to get the next level approver when expense owner=CC manager to avoid the user approving his own report.
