It is supported and works fine.
When you are in the VSC console within VC you can select which of the servers from Linked Mode that you wish to use. The location bar along the top that has like "Home > Solutions > NetApp > ServerName", if you click the server name you will get a drop down to select which of the VC servers you wish to use the VSC for.
Only thing you need to ensure is that you have access to the remote ports that VSC is running on from the workstation/server you are running the client from.
If you wanted a single pane of glass view for both VC servers inside the VSC then this isn't available as far as I know.
Hope this helps.
