Animation Composite

how can i play notifies from animation sequences in animation composites?
the thing is that i have to loop a segment of the animation composite (character idle) multiple times and doing it manually by placing sounds in animation composite is painful (consider that i have to do 10+ of those composites)

this can be done and works with animation montage, but i can’t get animation montage of my character work properly in level blueprint (it worked in UE 4.6!), so i have to do it with animation composite

thank you
