While in the drawing module, I have noticed that you are limited in what you can add to right pull-downs. For instance, while working in a drawing and you are in the Annotate tab or tools tab, you can't right click and add a function from another tab. In our case, adding a function from the Layout tab while working in the annotate or tools tab. I would be nice to be able to add any function you want to customize your pull downs. It forces me to have to change tabs. This would be a nice little time saver. PTC currently notes it as being working as designed.
