This is only for running in pupmode 13, where the save does not automatically update (pupmode 12), as things change.
I made this .desktop file to run the same thing the desktop save icon does.
Download it and place it in /usr/share/Applications
Save the change.
Run fixmenus, in a terminal, to get it showing in the menu.
May need to just do a save and a reboot, to get it showing.
It will be in menu->System
Note:
Rename file, removing .gz from end.
Had to add .gz to name, so it would attach.
