Yes, you would have to do what you said, but currently you still have to remove the morter board from on top of the bricks , bend down, pick up the bricks, move them to the next location by again bending down, pick up the mortar board and place it on the bricks...without the obvious advantage of not having to bend down everytime you need mortar...
My point being, even if it does add some time and is a little bit fidly to do, I'd say the pros definitely outweigh the cons!
