Transition between flipbooks in a 2D game


I am a beginner in Unreal Engine. I am making a 2D game and my character has a dash animation consisting of a startup, a looping sequence and an ending. I have prepared a flipbook for each of these animations. I know how to assign a flipbook so that the looping sequence is showing when my character moves, but I want to add the startup flipbook when I start moving so that it transitions into the looping sequence. When I stop pressing the button, the dash ending animation should play and transition into the idle animation. How do I do that? Thank you.
