Perpendicular dimensions with measure tool?

Hello guys,
I find measure tool to be easy to use and therefore really effective to create quick dimensions in my model. However I am missing this one feature that would make this tool even greater. I know that you can snap measure, or enable depth measure of an object with a shift key but IS there a way to create perpendicular measure with this tool? It would be super handy to be able to measure a distance between 2 objects that are not same size etc. See pic below to demonstrate my meaning.

Anybody?

Thanks
