fMod and blueprints

I’m trying to trigger a Level Sequence using a marker within an fmod event. I.e., when a certain marker plays on the timeline, I want it to trigger a matinee/sequencer animation of a door/platform. How would I do this? I figured out that within an object blueprint I can use OnTimelineMarker to appropriately fire off a signal, however I can’t seem to use this to trigger a sequence; it looks like sequences have to be triggered from within the level blueprint, and for some reason I can’t create a OnTimelineMarker node within the level blueprint.
I’m pretty unexperienced with blueprints so would appreciate any help.
