Is it possible to customize a removable drive launcher/quicklist?

So, I do know that it is fairly easy to customize application shortcuts (launchers) by editing the respective .desktop file. But, is it possible to create custom quicklists to the removable drives' launchers? E.g. a "Format" option or "Properties" would be really useful.

This is currently not possible because the menu items are hardcoded.

However, if you think that feature should be discussed, you can write a mail to the Ayatana mailing list and elaborate on why it should be included. :)

No, it is not possible. The pinning of the drives icon in the launcher isn't controlled by a .desktop file. It is added as UUID of the drive/partition. You can check this by using the command

 $ gsettings get com.canonical.Unity.Devices favorites 
 ['A80C1BD70C1B9F7E']

And for your information, In Unity version 5.14.0 (Ubuntu 12.04) there is an option named Format too. but no option with Properties though.
