Revit :: Lining Tags / Text Up

I understand that revit is the future and that it is very impressive at doing very complex & mundane tasks, however it does seem to struggle to do the simplest of commands.We wish to be able to put tags (in this case room tags) either in the middle of the room or align them all to each other (i.e if there is a corridor with rectangular rooms on each side of the corridor all tags on the left hand side would be in a single line in the middle of each room, as they would be on the other side).When you place the room it gives you some cross hairs but you cannot locate these in the centre of the room.I have looked for draft line/reference lines/ghost lines and anything that you can put in temporary to use as a guide.
