Our store gives store data access to our sales team to facilitate the understanding of a customer's full history with the dealership. This complicates our efforts at sharing mining segments, because we can't provide them with a segment that isolates their customers.

If there were a filter option in mining to filter by "Active User", such that when user Joe Schmoe clicks into a given shared filter he sees only his customers, but user Jane Schmoe sees only her customers, that would solve this issue.
