Shift Count for individuals in a Roster Period

Our part-time, casual (non-1.0 FTE) employees are required to fill a certain number of shifts in a roster period. Can we have a count in the roster showing how many shifts they have filled during that period? This will help us better plan our part-time workforce and ensure compliance with their employment conditions. We would need to set in their profile what they are contracted to work in a set time period, the roster would look to that for assessment.
