Room Retagging

Is there a way to remove all room boundaries and reselect to name?

Select the room name (and X will show up over the area) and hit delete on your keyboard. To remove the room name from in the list of rooms create a room schedule with a list of room names and delete the ones you no longer want

Thank you. From where can I Import Name styles as none are showing up

What do you mean by name styles? You can edit the tag family and make changes inside there
