Camera Rig and sequencer

So, my issue is that I want the camera to follow a closed rig and loop 3 times, then stop where I want it to stop so I can move it freely. However camera position on path only goes to 1 (I wanted 3.5). Adding a second track for position on path does nothing, post infinity is not an option either, and pre infinity does not solve the ending at 0.5 or it would loop only 0 to 0.5…
Any ideas?
Thanks

so my my only solution is to keyframe from 1 back to 0 in step… for 3 turns it would be much easier if the Rig supported values above 1 in closed splines.
