Ability to use "Users" as a source in a custom field Merged

Hello there. I read the recent blog article on goals/strategies and began implementing. A custom field called "Goal owner" is required, is there a way to tie this to the users data-source in Aha! as opposed to have this be a text field or an independently managed list of owners which is really users???

I'm not sure I would implement without this and then have to fix data quality issues.
