Using a path to crop but need it to crop outside document bounds

@ jazz-y This is perfect! I can actually just draw my path as an unfilled shape to begin with and save a few steps. Thank you!!

"The action only records the specific area I'm cropping on whatever image I'm using to make the action."
Change Ruler unit to Percent when recording step what will force Photoshop to record percents instead of pixels. In this way you can record step to insert path which is always 100% of image width instead of inserting path 1500px long. See screenshot below, same path differently recorder will produce different result when you run action on image file 1000x667px. The first step with percents will cover entire image with path while second step with pixels recorded will draw path waaay beyond image borders.
