Distinguish Different Locations and Options to Filter Them to Users

Summary:

We have 10 Locations (LOC1 to LOC10), out of which first 5 are HR Locations and should be available for assigning employees to them via Department & Position. The rest 5 are Finance locations needed specifically for maintaining Lease data. The latter set of Locations should not appear to HRs to be assigned to the employees. All 10 locations should be under the same Business Unit BU1.

How to achieve this?

Content (required):

We have BU1 in Reference Set SET1. We created LOC1 to LOC5 (HR locations) in SET1 so that these Locations are available to be assigned to the Employees. However, for the LOC6 to LOC10 (Finance locations), if we create them in a different Set, say SET2, these Locations do not appear to the HRs as HRs do not have access to SET2. In this case, the purpose of HRs not being able to view 'Finance locations' works. However, this in turns does not allow us to link Finance locations to the same BU1 as BU1 is in SET1.
