Filtering worksets under same role for users with different portal desktops

Hi Experts,

Any inputs for achieving the following idea in ESS implementation.

For X country -> workset X (Personal Information PCD content created)

For Y country -> workset Y (customised iviews,pages Workset for Personal Information created.)

I want to avoid creating two ESS roles for both X and Y country as other worksets(entry points are common).

I want to display at runtime X and Y worksets respectively to appear for the country specificuser (desktop) .

Here i have tried

- Created workset Y with filter id.

- Created USER_GROUP_Y for country Y with a portal desktop rule with filter id.

- Assigned the workset Y to ESS role.

- When logged in as Y country user , i see both the worksets X and Y

How to achieve filtering two worksets country based using SAME GLOBAL ROLE?

KR,

Swathi
