The Add to Room/Activities menu option allows you to assign a display to a specific room. A display can only be assigned to one room.
Click the user account icon in the top right and select Admin.
On the side menu, click Displays.
Click the icon next to the display name and select Add to Room/Activities.
Check the box(es) next to any activities to which the display should be added.
Note
Only one room can be selected. If the display is already assigned to a room, attempting to select a different room will result in a warning that doing so will remove the display from its current room.
Make adjustments if necessary, then click Add to Room/Activities.
