Well on Patch 6 it seems the bonus action for great weapon master, i.e., when you strike down an enemy can be reserved till next round. So you may jump, kill someone, and strike twice for your next round(1 normal action, 1 bonus action which is passed from last round)
Oh, gotcha. You were saying that it can be reserved for the next round in BG3, where in reality that shouldn't be allowed. I misunderstood.
