Should be possible to separate menus from shared like user dimensions

With shared user dimensions, it is possible to separate those by right-clicking the user dimension in source data and choosing "detach from shared". 

That has 2 advantages - you can now share the analysis with someone on another TARGIT solution with the same source data, and you can do a local version of the user dimension without affecting the shared user dimension.

A similar option should be available for shared menus if you decide to make a "local version" almost identical to the shared menu.
