Increase Outline by #5 for Building Pad

Howdy,

I frequently have to determine outlines based on being larger than a design structure. Examples are a building pad needing to be 5' larger than the building on the plan, or a parking lot excavation needing to be a foot larger than the defined parking structure.  Is there an easy way to do this?

Currently, I add measurements all over the place from the designed structure to whatever outline I need. It just takes more time/tedious than I'd like so I'm hoping for a clever solution.

Thanks in advance!
