Change Sequence in AnimBlueprint from outside

In AnimBlueprint i can add nodes “Play XXX”, where XXX - constant anim sequence from assets. Can i create variable of AnimSequence ref type and use given sequence in pose blending? So i can have sequences like “WalkNormal” and “WalkLame” and just change actual sequence from outside blueprint. Making this through states inside AnimBlueprint is not flexible enough. If i create new sequence, say “WalkStunned” - i need rework whole blueprint again. Or maybe i can use other AnimBlueprint like “subroutine” in main AnimBlueprint?

Thank you

Looks like “Play slot animation as dynamic montage” resolve task
