Nor do I have such a sled- I use a sliding table saw which is similar in operation to your left-of-blade sled. I use the retracted rip fence as a bump stop frequently, but it requires that the work is long enough to register solidly to the crosscut fence. For long cuts I have a telescoping extrusion with an integral flipstop.
A story stick (maybe a 1 x 1 the length you want to repeat) can make setting each piece in place on the sled quicker and more accurate than measuring and marking each piece.
