We have a requrement to design a report model that is unique to each state users.

report models created and deployed to report server. and now when users log into report server they only see the report model and data source for their state and they have only report builder access, no site setting,no any other setting.This is done by role assignment and item level security,no problem.

The problem is when a user runs the report builder he/she sees all the report models on the right side window of the report Builder,rather we want the specific model to show up.Please shed some light on this
