Add Admin Bar Menu in the Network

Hi,

I want to create an admin bar menu (with submenus) in the network so that all the sites within this network can see the admin bar menu. So, if I change some menu in the admin bar menu, all the sites in the network will see the change. Note that I want that the menus link to dymamic pages (such as pages, comments, posts, etc) according to each site of the network.

Is there some plugin to do this? Or do you know the code to implement this?

Thank you for your attention.
