Control Timeline from Separate Actor / Collision of specific static meshes

I may be going about this the wrong way but I have Actor-A (a slider lever) and separate Actor-B (that has multiple timelines that move various Actor-B Static Meshes). When the lever goes to position one it plays timeline 1, position 2 timeline 2 and so on. I’ve tried adding Actor-A as a Child Actor Component but can’t seem to get it to register a collision on that either.

My questions are these.

  1. Can you control Timelines in Actor-B from Actor-A directly.
  2. If you can’t cross control timelines - Can you register a specific StaticMesh in Actor-A collision with a specific StaticMesh of Actor B.

Option 1 - Actor-B detects collision of StaticMesh1 in Actor-A and triggers timeline.
Option 2 - Actor-A (lever collision within Actor-A) directly triggers Timeline 1, 2 or 3.

thanks
