You can use the manual placement method and create a zone of any size/shape you want.
But if you also want the individual room zones to be there as well you may experience some issues with overlapping zones if you are trying to get information from schedules.
You could try adjusting the placement height and overall height of your group zone so it doesn't pick up doors and windows but will still give you an area.
It all depends on what information you are trying to get and what setting you have in your schedules for filtering criteria.
Or you could just use a fill if you don't actually need a zone as such.
