Owner field for templates/multiple user fields

There should be a user field option that is able to populate based on CMP users and can designate as 1 user, team, or multiple.

For example, we have a campaign owner field and instead of having an open text field, and we'd like to set that as one of our specific team members so that we could filter for campaigns owned by a certain person. We currently use an open text field, but this leaves room for typo errors as well as someone only entering a first or last name, etc. This owner field would be like a dropdown in the templates. When you type the name of the user, the name will appear in the list, and you can click on it to select. No need to type the name.
