Allow custom "Hubspot user property" as filter for Company/Contact access

As of now, Hubspot only allows admins to set the level of CRM access for users based on 3 factors: Everything, Team Only, Owned Only. 

While Everything includes.. everything, the other 2 options use Hubspot's Company Owner, Contact Owner, and Deal Owner properties to determine ownership.

 

It would be so incredibly helpful if a 4th option on this list was "Custom Hubspot-User Property" - essentially allowing you to create your own user-based property for CRM access purposes.

 

So often we want to grant access to a select group of companies without changing the default "Owner" of the company - having the ability to filter using a different user property would help tremendously.
