Some of my server names are very long. For example managed instances names end with 'database.windows.net' They make the tabs very wide and harder to read.

Is there a way to instead of using $Server$ in the SSMS Caption setting to use an alias? So instead of the long name for a production server for example, I want 'prod' to display in the caption for server name. 4 letter name is much easier to read than a 50 character name, specially when there are server names which are very similar. 

I can use the Tabs color feature and remove the server name but when I have many servers, it's hard to remember which color goes with which server and every server will need its own color.

If this feature doesn't exist, I would like to see it implemented.
