Spot Elevations on Ramps

When you place spot elevations on your floor plan, if you try and place them on ramps you will notice that this isn't possible using the spot elevation tool.

It is possible to place them on elevations and section but plans it isn't possible......or is it?

A simple work around is to place the spot elevation onto a floor and then move or copy it onto the ramp and magically it will host itself to the ramp levels.
