Over the last few months I've started to stretch my images prior to printing so that all of my prints come out with uniform image areas, no matter how I cropped them. This makes it really easy to re-use mats, everything gets printed to one of 3 ratios. However, I'd prefer to be able to do this on the fly when printing my master file from Lightroom, rather then storing extra files for printing from PS. The problem is I can't find any way to do this in Lightroom, it appears to be crop only. Am I missing something?
