I haven't mess with Poser dynamics since Poser 5.

I don't know even if Pro 14 could do what you want.

but with Poser Pro 12 I guess you would rig one end or attach a ball "make the ball invisable at render" and drag the rop across everything.
after you made the rope dynamic.

 

your just half to test things out and see what works.
