On Position pages make Location LoV dependent on Business Unit selected

Hello Experts

When system was configured all Organziations have been defined as "Common" it is still the correct procedure for us specially because we have many interconnections of hierarchy , and need sto move department in tree logic etc.

The point is in all HR pages, specially for Positions
The Location a1 and a2 is supposed to appear only when I've selected Business Unit A.
The fact that I select BU = "A", and appears locations b1, b2, c, d … that allows users to missclick and wrongly select the location.

Is it possible to limit the option list of Location based on Business Unit chose?
