Customize and save Export As options

One of my tasks at work is adding and updating images for our store. Each product has a large, normal and thumbnail sized image. Our standard sizes are 500 x 500 px, 250 x 250 px and 125 x 125 px with corresponding suffixes. What I'm looking for is a way to set the Export as dialog to these defaults and suffixes and have them pull up as the default setting every time. The export as feature is handy but I spend a lot of time reconfiguring it every time for each export. I could fly through adding new images if I could save these setting but I see no ability to do this in the preferences other than setting the export format and quality. Is there a preferences file I can manually edit for this or is there some hidden ability to save these setting I don't know about?
