You can put this into a wrapper script, and call the script from the
desktop file.

In fvwm-crystal, sh scripts are created from the desktop files, and the
application menu call these sh scripts instead of the desktop files.
These sh scripts can be customized or masked at the system and user
level, and custom scripts can be added at both levels, which give a
total freedom to both the sysadmin and the user.
