A contact property with the field type “hubspot user” can not be used in a form. This makes it difficult when using formsAPI and you want Hubspot to receive a contact owner from another system. Maybe it could work if we created a dropdown select with all of our users and then created a workflow that copies the value from that dropdown select field into the contact owner field. But that would be a nightmare to keep updated when having a lot of users. Ideas?
Hi, @ClaraSoderberg 
Thanks for the interesting question. I feel like you are on the right path with your idea. I am too am curious if there is a way to automate some of this.
Hey, @nikodev @LMeert @Teun, have y’all tackled anything like this internally or for a client?
Thank you for taking a look! — Jaycee
