Possible to adjust platform icons to include commandline switches for triggering applications?

Hello:
Is it possible to change the platform icons/shortcuts? to include commandline switches for individual portable applications? For example I would like to be able to by default start Notepad++Portable.exe with the -multiInst switch.

I was expecting to be able to adjust the shortcuts in the Portable Apps menu via right-click but the only option is to rename the shortcut.

Am I missing something?

Thank you,
