Cannot specify qmake for Docker under Windows

I am trying to move my docker image from the public facing one from docker.io to a private one that I can share. I have most of the settings transitioned over to my private Container, however, this setting cannot be changed on Windows, because when I navigate to the qmake directory, it only allows me to choose a qmake.exe or qmake.bat file, and not a qmake file (with no extension).
