To restrict a **multiple users** field and allow only one owner, open the field settings and turn on the option that limits selection to a single user per record — instead of the default that allows several at once.

## Why does limiting this field matter?

In accounts with many users, leaving the field open to multiple selections can create confusion about who actually owns a process. A sales opportunity or a ticket without a single owner ends up with no one taking responsibility for resolving it.

The problem is even clearer on large teams: listing "all users" as the default option forces people to type out full names just to find who needs to be assigned.

## How to configure the field

1. Open the **multiple users** field on the table you want.
2. Turn on the option to restrict it to a single owner.
3. Save — from then on, selecting a new name automatically replaces the previous one, instead of allowing two at the same time.

| Behavior              | Before                   | Now                              |
| --------------------- | ------------------------ | -------------------------------- |
| **Default selection** | All listed users         | You choose who shows up          |
| **Owner limit**       | Several at the same time | Only one, if configured that way |

### FAQ

### What happens to records that already had more than one user?

They stay as they were until edited; the new rule applies to selections made after the change.

### Can I switch back to multiple users later?

Yes, just turn off the restriction in the field settings whenever you want.

### Does this setting apply to the whole account?

No, it's applied field by field, table by table, based on each process's needs. Learn more at [jestor.com](https://jestor.com/?ref=blog.jestor.com).
