You can simply copy paste any object from plan section or elevation in complex profile draw window, which later can be used as per your wish. I think this will help you to get your required end results bit faster.
Cannot agree more, it is an essential wish. Also. if one selects an existing profile or element to turn into a complex profile in a view that cuts the element perpendicularly (i.e. wall in section or column in plan) then default behaviour should be to open profile manager with that view as a trace.
This wish is really long overdue.
