Does a "retractable" soft top exist?

I was wondering if they have retractable soft-top covers out there. You know the semi-trailers that have the covers that are on rails (pictured below)... Something like that function, but with a soft-top cap.



This would be a great feature because I would love the extra room I would get vs. a roll-up tonneau cover, all while being able to retract it when I want to load the quad into the bed...



Anyone see one before?

Or even an easy "lift-off" hard-top cap. Something that may use a couple alignment pins, but is held in place by 4 latches or something... Then I could rig something in my garage ceiling to hook it and lift it off the bed...

Now I'm just just spitting fantasies...

 

My softtop brand top on my first gen taco would fold and lay flat either behind the cab under the rear window, or above the tailgate easily. Not sure if that is exactly what you're looking for. The soft top on the 2nd gen in the picture you posted looks the same as mine did, so I imagine it could do that also
