Sweep 1 "stairlike" option?

Hello,

Currently i cant see a way how to sweep a profile along a curve to keep profiles axis constrained to the plane.

1 - single rectangle is swept along arch freeform style which is not different to roadlike in this case

2 - what i wanted to achieve is only achievable with multiple profiles oriented along the rail

I think 2 should be achievable by simple command input “stairlike” likewise in arraycrv command
