Sequencer pausing itself

Hey guys, I’m very new to unreal, currently working on my first project. I am trying to play 4 separate sequences in a specific order, each after the player activates one of 4 separate triggers in a random order.

My plan was to combine all sequences in one main sequence and make the sequence pause itself after each sequence with keys on an event track between each sequence. So it will resume with “play” with the next sequence after the next trigger is activated. I am struggling to make this work; I can’t seem to make the sequence pause itself. There is probably an easier way to do this? Would appreciate any suggestions, thank you!
