Customize User property Tokens

It would be great to be able to customize "User properties". We use this to personalize our automated marketing emails, but it's restricted by fields that Hubspot provides. 


In our case, we would like to have a token with a Zoom link of the assigned Customer Success manager of a contact. 

The screenshot below shows the available "User properties" we can use at the moment. It retrieves the information of the Customer Success manager of the contact and becomes a token in a marketing email.


Would be great to have an option to create custom User properties!
