Adding services to a new role in ESS

Dear Friends ,

I've created a new role HR_Admin in Content admin->Create new role and assigned it to HR admin.

Previously I've created HR Admin Self service in LPD_CUST under ESS Menu.

Now I want to move entire HR_Admin self service (It includes all standard HR transactions like PA30/PA40/, reports)  to the new role under HR Admin folder as it is different from ESS and to be given to only HR Admin,

Please guide me how to do this?

Regards,

Niladri
