Build the USB Breakout Board
The first thing you'll need to do is make a tiny USB type A male connector breakout board that's the same width as the Pro Micro.
I've included the KiCad files and zipped Gerbers. You can order them directly from OSH Park or mill them yourself using something like the Bantam Tools Milling Machine. To get them, click on the button to download the GitHub repository and search for the "USB_Male-gerbers.zip" file in the .../USB_Male/gerbers directory.
Once you have the board made, solder on the USB connector. If you make a 1-sided board like I did, you'll need to solder the connector on the top side.
