Core - Associate Location to Business Unit

Hello Experts

When our users are cretaing or editing Positin after selecting Business Unit the list of all available Locations are displayed.
We have a corrrelation between Location and Business Unit that is in most case 1xN no location can be used for 2 different BUs

Is there any way to force the correlation between Position LOV with BU?
Legal employer and Busines UNit already have this feature as an EFF delivered: Associated Legal Employer (PER_ASSOCIATED_LEMP)

If we had this would be a lot less entries of wrong information being inputed.
if not possible I shall open a new ER.
