1. unfortunately ae not natively support type of operation because user can't access path vertices coordinates easily. can this script bao mask avenger 2 - aescripts + aeplugins - aescripts.com have used myself , handy. through script can create live nulls attached path vertices (masks or shapes) , once have that, can many things , attaching object 1 of them. it's cyber monday 25% off today btw.

 

2. if path has 2 points, can use beam effect comes 2 position cross-hairs on each edge.

 

3. manually if it's not complicated , adjust keyframes eye
