not out of the first dash you doYou can dash attack on frame 1; you just have to let go of the stick before pressing A. I think you can also just input it like a tilt if you are dash dancing.
if you let go of the stick and press a before the 4 frame window has passed nothing will happen
and btw there is only a 1 frame window in a dash dance to pivot something
though if you only tap the direction for 1 frame, you will only turn, and then stand which would make it easy to pivot something
but if you are just dash dancing, there is only a 1 frame window to pivot
