App shortcuts in XFCE

I am referring to the dropdown “Q” menu that lists your various VMs and

the software in them.

I was used to the KMENUEDIT in KDE. It was easy enough to make QREXEC
shortcuts.

The new R3.2 defaults to XFCE in a clean install. I didn’t see a way to
edit those menu items the same way. Sure I can add more shortcuts for
programs that are installed and generate .desktop files. The problem I’m
having is with the software or executables that don’t show up in the
shortcuts list. For example, portable apps; You don’t install them you
just run the .exe

Is there a KMENUEDIT GUI equivalent in XFCE in Qubes to edit those
menus?
