iNotes customization - how to add a custom action to an existing sub-menu

I’m familiar with the options of adding custom actions using the addActionsLite helper function, as well as “removing” sub-menu items from a given menu using “removeActionsLite”. Question is:

Is there a way to add a custom action to an existing sub-menu tree? To be exact: I’d need to add an action to the “more” menu tree. Is this possible?

Best regards,

Lothar
