In the next update of Ventoy (1.0.45), you should really add this feature.
It's very quick to implement. Just drag the code from the first post in this thread into grub.cfg (replace functions for menus). Then users of this wonderful tool would just have to create "F2.cfg", "F4.cfg", "F5.cfg" and "F6.cfg" files in the "Ventoy Submenu" folder to modify the Ventoy submenus. When upgrading, all the customization will remain as before !
I tested everything and it works perfectly without changing the rest of the Ventoy structure!
