Parallel toolpath in a pocket

Hello,

 

I sometimes have to make simple ramps from plywood and I have found parallel toolpath along the ramp with a flat endmill gives me good results. I would like to extend the parallel toolpath tangentially along the ramp to make sure it doesnt leave cusps where it changes direction, but I havent been able to do that. Also I need the ends of the ramp to start and stop at precise locations but the parallel toolpath starts somewhere close and usually ends when there is no room left for a complete stepover. I would like something like a 2d contour with open contour and start and stop extension and roughing passes, but that doesnt work with my setup on  a 3 axis machine.

 

I tried a flow toolpath as well but it has similar problems with start and end locations. Included is a file and picture with highlighed surfaces I want to machine.

 

EDIT; Morph toolpath seems to work ok, but I still cannot do the tangential extension of toolpath. As a workaround I modeled the part larger in x and z direction and offset my origin accordingly.
