Segmentation Model - Authorizations

Hi All!

I need to control authorizations about the customer data base when specific user roles use the graphic segmentator.

For example, User 1 is the responsible of 1000 Sales Org, User 2 is the responsible of 2000 Sales Org, User 3 is the responsible of both.

When User 1 try to segment we need to filter only customer of 1000 Sales Org.

When User 2 try to segment we need to filter only customer of 2000 Sales Org.

When User 3 try to segment he has the entire data base to segment.

Can anyone help me? any idea?

Can we do authorization by, for example, Segmentation Basis?

Thank you.
