This is super necessary!
We used Calendly before and they offered this option. As we want to simplify things we would like to only use HubSpot. This is actually a real problem and makes things more complicated.
Also, I would expect to add some criteria which prioritize specific HubSpot Members.
For example, Sales Member A is being prioritized for all contacts from the USA and Sales Member B is in charge for all contacts from China. This way the contacts would get assigned directly to the right person.
Since there are so many properties in HubSpot I think this would make things way better and more useful.
