Profile Management - Eperformance

We currently do not use Profile Management, but would like to use it for ePerformance. Outside of the system, we have content Items categorized at department level (common for all employees)  and  at job code level.  

If we we define two  profiles, one at department level and another at Job code , then eperformance is pulling the  content items from profile identity that is having the highest priority only.  If we define only at job code level then we have change all the profiles for any update in content items at department level.

1.Is there a way to overcome this restriction or better categories the profiles so that we don't have to change each profile if there is any change in content Item at department level?
