Animation Montage in Level Sequencer?

Is it possible to play a montage (not animation sequence) through a sequencer?

I’m using 5.4 now and I’m trying to build a VFX sequence. I’m using montage cause I’ll be adding Niagara through the anim notifies. I’ll be playing the montage multiple times through the sequence, so I would love to play it from the level sequencer, but it seems impossible.

In the sequencer, the animation slot for a skeletal mesh only shows animation sequence, not montages when I hit the + sign. Any suggestions?
