Display Room Number in the Online Check-In

I would like to display the room numbers in the Online Check-In so that guests with group bookings can identify which room they are currently completing the Online Check-In for.
For group bookings, it is often not clear to guests which room they are currently completing the Online Check-In for. How can this be resolved?
To display the room number in the Online Check-In, go to settings/web-booking and enable the "show room" option under "Online Check-In Extra Information".
