Used to come close...
In the early 80's when ASNSW had a concrete slab at Mt Bowen, I had three marks on the concrete and was routinely able to set up a C8 roughly aligned on to the pole, straight out of the car; usually it was within 1 or 2 degrees and easily corrected from there - and it was routinely good enough for 10 min shots with a 500mm lens.
Repeatable setups should be possible if you have a regular observing spot on a solid surface, and the mount mechanically will preserve the alt/az adjustments despite being repeatedly disassembled/reassembled. Some mounts will, some won't.
I'm also tempted to put some small holes in the stone at my regular haunt, for the same reason.
