Exporting Multiple Dimensions

[mattdesl]

I am working on a print series and realizing I probably want to give buyers the option between multiple sizes, rather than forcing them to a single size. I'm also realizing I usually export multiple sizes: print, Behance, IG, Twitter sometimes all get slightly different sizes, sometimes working in inches or in pixels.

Will have to think about syntax... but should be possible so that Cmd + S will save all sizes in a single go.

EDIT: Just thinking, maybe this could somehow be done via a UI or somehow without code changes. I do not really want to associate exact combination of sizes with a git commit, because some time later I may revisit the same artwork to re-print it at a different size, and I would like to be able to just git checkout that SHA and re-export without tweaking any code.
