Yes, I have made 1,2,3 and 4 step ladder- style aiders out of 1” tubular webbing. To keep the steps open I threaded the webbing through about 6” of pex tubing and then put camo tape over the pex.
I basically started with one big U-shaped length of webbing and then sewed 14” lengths of webbing fed through pex as steps - 6” of webbing for the step portion, 4” of webbing attached to each leg of the long webbing.
