How to prevent querying service requests from Create Service Request Form across operating units

Hi,

We are using Field Service on 11.5.10.2. The module was being used on a single operating unit but from now on we will have another operating unit. Our expectation is preventing users from seeing the service requests of the other operating unit.

There is a profile which filters the service requests on operating unit basis on Find Service Requests screen (Service: Default Operating Unit in Find Service Request)  but we could not find any standard way of doing it on Create Service Requests screen while querying.

Is there anyone who had the same goal and found a solution for this? Any recommendations?
