I don't really think about it much. If traffic is heavy, I just hold the paddle for a second and it switches into B5.
Similarly, if you want to go back into D, you can hold the opposite paddle for a second.
? Pretty sure mine doesn't, I have long wished it would go all the way up or down by a long hold instead of a short press but it doesn't for me, have to press multi times.
