RSRP-469180: Treat a simple assignment switch block as "simple"

in C#: Treat a simple assignment switch block as "simple"
i.e. allow reformatting as follows:

     private string demo(int v)
     {
         string rc = string.Empty;
         switch(v)
         {
             case 1:   rc = "One";                 break;
             case 11:  rc = "Elevent";             break;
                case 101: rc = "One hundred and one"; break;
         }
         DoSomethingWithValue(rc);
         return rc;
     }

Currently only a "return value" is recognised as a simple case statement. Currently, the above code is always re-formatted with the break on a new line - which I do not want in this simple case.
(It would be appropriate to consider the choices when the line length exceeds the wrap margin).
There are two considerations here: allign the simple statement (or not); align the break statements (or not).
