Select the palette. In my case "Grays"
keyboard shortcuts and search for 'palette map' assign to a key.
load the image
press the assigned key

Still not sure why you want to use this method to make a grayscale picture. This degrade the quality, compared to Colors > Desaturate > Desaturate (32 levels of grays instead of 256).

And my suggestion to skip the file dialogs still holds.
