Adding console command auto complete for the client

Console commands can be added from the server, to be ran by either players or the server itself, OR they can be added clientside. Doing both will make it so the server is never informed of the client’s usage.

This means that the autocomplete aspect of console commands added by the server can’t be seen by the client.

Does anyone know a way to arbitrarily add an entry to the client console’s auto complete list? Do I need to instead use all clientside commands that net message the server to inform it?
