Suggestion/How Do I Edit

I see how to EDIT the categories to put in an icon

BUT isn't there any easier way instead of 1 category at a time?

A possible suggestion is to ADD the icon when creating the category that would be so much easier. I've had to manually create 200 categories, upload all the images and now have to go to edit each category go to the image selector and then type in the search for the file name since I do not know all the icons.

I'm creating categories for all countries of the world, so I do not know all the flags by site. Would be easier to see the file names instead of the images too.

Any ideas?
