Connection patcher and Wow.exe

Hello community!

Id like to ask: how can I add a default server realmlist (portal) when the user start the wow.exe?

I thinked of this:

When I cmake and compile the core, is there any ways to edit the connection_patcher to update the wow.exe in a special way, to force change the file (or creating a different named one) to a specific port (not the base “EU”) and when the user change it manually, its caunged to the specific one when the wow.exe launched?

Or this can’t be?
