I would like to be able to customize the PXE Boot Menu like so:

Get to the Menu Selection

1. Auto Image for GX240
2. Auto Image for GX260
3. Auto Image for GX270

And when you select a number, it automatically starts my gx240.zmg file
without having to navigate through all the other windows to get to the
screen that asks you for the UNC path of the file.

Is this possible? If so, any assistance would be greatly appreciated.
