TOAST /image from a .DLL

TOAST presently allows one to select the image file to be displayed with the /image option.

I would like to suggest being allowed to also select an image from a dll. For example;
Code:
toast /image="shell32.dll,-154" /expire=15 /action=Yes /action=No /text1="Do you want to try to take over the world?"

I can presently do this using NirCmd.exe;
Code:
nircmd.exe trayballoon "Hello" "This is the text that will be appear inside the balloon !" "shell32.dll,-154" 10000
