Hello
It had thought that for the most impatient travelers would be able to be installed a lever in the entries. This lever would permit to change the entry without the need to expect time. The price could be of a unit of energy and perhaps would be able there to be two levers a to left and another to right to change the direction of the mechanism. A greeting and thanks.
Wait, do you mean levers on the elevators to instantly punt you into the next level? The delay between clicking "descend" and the lift setting off, as well as being extremely short, is due to the lift waiting on input from everyone in the party, and serves to ensure that all party members arrive in the level at roughly the same time. If you don't care about staying with your party, just go solo.
