Custom Owner Propierties work well for Users and Permissions; when assigning the following permissions to a user [See Contacts > Team only], HubSpot takes into account users from HubSpot User Property + User Custom Properties.
However, it doesn't work well when trying to filter a list or a report by Owner or Team properties; some examples:
1. When trying to filter contacts by Owner, it's only taking into account official HubSpot owners and no owners from custom owner properties.
2. When trying to filter contacts by Team, it's only taking into account official HubSpot owners and no owners from custom owner properties.
3. When trying to filter dashboards or reports by Team, it's only taking into account official HubSpot owners and no owners from custom owner properties.
I th would be great if Team/Owner filters take into account users from custom properties. Custom user properties are essential for big companies that share customers between Business Units (same Contact/Company, different owners).
