I have the same problem (slow list loads because of network), while your idea is much more automatic (and I would perfer this), you can make a .map file using Excel and ASAP Utilities' Import File function. I haven't got around to actually doing it, but you can import a list of the files in the directory, then I copy another column and Replace ".zip" with "" (nothing) to make my name colum, then export the whole thing to txt. A little messy, but a doable solution.
