Change asset order in Asset Export

Is it possible to organize the Asset Export window? I would like to be able to organize the assets in the window so I can visually group them together by type or name. If I have 4 different button graphics at the top of my asset list followed by a bunch of other assets I would like to be able to add another button graphic to the Asset Export window and put it next to the others. Currently it just gets added to the botton of the list which isn't great if you have a long list of assets. This feels like a no brainer. is this really not possible? I would love the ability to sort the list by export name. that would be the best.
