How store drop down work in SIM application

Hi

We have more than 200 stores for our client. If a user has access to only2 stores in SIM then he needs to use stores: DROP DOWN to select his specific store out of 200 stores fom SIM application. It is very difficult for user to find his store out of 200 from drop down.

We are also using OID with SIM for user access

Can any one advice that how a user can see only his specific stores in SIM screen dropdown and not all stores to select his particular store.
