Canary Calculations %Path% Variable Support

Currently in Calculations, %Asset% is supported which makes building dynamic calculations easy. Still though, you have to manually type in the 'Path' portion even if it is selected above. In the example below, I have added the Path to the Asset Context already. It would be great if I can just refer to it as %Path% instead of setting it twice. This makes it easy in the future if I ever want to modify my path, I don't need to do it twice for everything.
