We are looking for the same feature. We have many Brands with multiple locations and atm is impossible to add them to the platform. This makes it so much harder to manage them and does not allow us to fully migrate to Hubspot, having to work on two separate CRMs - hence not opting for the paid version yet.
Also the hierarchy of the Companies (Parent-->Child) is a bit confusing on the platform. I would have expected it to look more like:
+Parent Companies
- Child Company 1
- Child Company 2
- Location 1
- Location 2
- Child Company 3
etc…
