In 2d sketching, is there a way to ensure a point is coincident to a finite line segment? The basic coincident constraint merely ensures the point lies on an infinite projection of the finite line segment. I would like it to stay within the line segment.

I'm using solidworks 2018 if that helps.

EDIT: To clarify, I would like the point to be freely movable as long as it doesn't move off the finite line segment. It's kind of like the path mate, but for 2D sketching.
