It would be a game changer to be able to select custom user properties for the meetings scheduler.
Example scenario:
In an account with multiple business units, that have overlapping contact records (one person might enquire with multiple business units/brands) we have a separate custom contact owner property per business unit (separate sales teams in each business unit). Issue is that the meetings tool only considers HS default contact owner properties. The option to select from a custom user property would come in extremely handy.
This should be applied not only to 1-1 meeting links but also round robins and groups.
To fully function with round robins - it should be able to apply teams to custom user properties as well.
