Inferior alignment in stair railing (offset instead of displacing path)

[Anonymous]

I'm trying to model accurately some stairs with their railings. In this case, the railing is aligned with the inferior face of the stair structure (attachement 1). When I edit the railing structure I can control movement in y axis, but not in x. What I need is actually an offset from the standard railing path.

I already tried modifiying slope and height of individual segments (attachement 2) but I end up with a fragmented railing.

What about a Landing Height Adjustment?

That works for the exterior panel, however, the handrail is not aligned with the upper part of the exteior panel. Is there a way to displace it on the x axis?
