Running a custom cog and shell menu

[Myoldmopar]

Greetings,

I'd like to inject a menu item into the cog menu (farthest top right in Unity...can't remember the proper name) for my own personal use. (It is a secondary suspend item which runs a script prior to suspending...and only used on certain occasions.)

If it is possible to inject one via an API, that would be fine, but I am also fine running a personal branch of whatever program manages that menu.

Any thoughts or pointers?

Just noticed I put cog and shell in the title, which came from meaning cog and spanner (the system settings icon). Though I'm not sure the top right icon is actually a spanner...ramble ramble ramble
