Is there any way to add a menu item to an existing group in the menu? I'm using tasks, and the _extra_actions_default sets up a SchemaAddition but I guess path is only able to refer to submenus. E.g. "MenuBar/File/OpenGroup" can't refer to the group named "OpenGroup" in the File menu.
I sort-of kludged it by adding a Separator called OpenGroupEnd after the group and referencing that as the after condition. See attached.
