Emit particles from Polyline / Line shape

I believe this is not supported, and I suspect it might be too hard (out of scope), but just in case.

I'm using Shapes as mainly a line renderer. I would really like to emit particles from the line that I'm procedurally making. The built-in particle system in Unity supports emitting from a mesh or a mesh renderer, but I don't think Shapes exposes these. I'm not even sure if Shapes uses Unity Mesh Renderer components.

Would it be possible to use the mesh generated by Shapes to emit particles?

Thanks for the help!
