Is it possible to create content and link it to an existing menu item? I have a menu tree with links all directing to 'front'.

On creating content I don't want to create a new menu item but want to have an extra option under the Menu settings saying 'Add content to existing menu item'.

What is the best way to achieve this or is there a module available that handles this situation (D7)?
I guess you have to write a custom module. This may be a similar situation.
