Revit :: How To Change / Set Work Plane While Sketching Path Of In-place Model

Possible to change/set the work plane while sketching the path of an in-place model? This guardrail extension is an example of where I would have liked to change the work plane while sketching the path because the path shifted planes. I believe you can do this in the family editor, but I could not get it to work in the in-place modeler. What I ended up doing (as an experiment) was to create masses and picked their edges to get the path I wanted. I would love to be able to have more control over the work plane, like defining the workplane by a face and then being able to move it relative to the face selected.
