In the venue that are a number of fixed locations. It would be good to be able to create a textual alias list somehow e.g.
Bar 1 : x= -3 y = 0 z = 7
Bar 2 : x= -3 y = 0.2 z = 7
Then when you can type in a number you can just type "bar 1" in to say Y and Z and the position will be know.
Then of course you can update the alias or as I would call it 3d palette and everything would move as you might expect
