Hi Jay, thank you for the answer, after messing around a bit I have stumbled upon a problem with your approach.
In my case I would like to add the person that is submitting the form into a multi reference field since all people that work at the company will be linked to the company in this way (this is submitted in the companies dataset). it would not work with the owner field since you can only link 1 person. a company can also be created by an admin and afterwards a user can link themselves to that company. in that case the admin should also not be the owner of the item. Would you have any idea how to solve this issue?
Many thanks!
