Redwood: Can you limit parent position LOV to positions in same business unit or legal entity?

Content (please ensure you mask any confidential information):

In the Redwood pages for position management (create, update etc.) I would like to be able to limit the LOV of parent position to only show positions within the same business unit or legal entity as the position that is being created/updated is located in. Is this possible? We have created a solution for this in the responsive pages using page composer, and going back from this will be a big downgrade.

We have around 120 separate legal entities with their own HR organization, and it's quite problematic if they are shown all positions from alle the other legal entities.
