Information Steward security roles with different access levels in same project.

can we create two roles with different access levels for scorecards in same project. Let me explain the scenario to better illustrate the problem: Project A has two score cards "Customer" and "Products". Can we create roles 'X1' and 'X2 ' where X1 can view Customer scorecard but not the Products scorecard and conversely X2 can view Products scorecard but not the Customer scorecard. Another similar scenario, Can we create roles 'Y1' and 'Y2 ' where Y1 can run tasks associated with Customer scorecard but not the Products scorecard and conversely Y2 can run tasks associated with Products scorecard but not the Customer scorecard.
