Does a advanced "wowusonly" option exist?

Hi,

I'm playing WOW on US servers from South Korea and connect to West Coast servers with about 140ms latency (not too too bad) - however when I get stuck in a Cross-Realm group where the group leader is from Oceanic and placed on Oceanic servers, then my latency goes above 400+ms. My normal latency direct to Oceanic is about 200ms.

Is there an option like you provided below for the Asia>Australia | Cross-Realm US server fix .. 'wowauonly' ... something like a 'wowusonly'?

1.4.8 Update was released. Re-open the application to download update.

There is Temporary server to use while there is this routing issue.
If using a SY/MY link to Sydney then under connection -> Advanced you should use custom setting: wowauonly

This will connect game to Wow Oceanic with Battleping, and USA server with ISP, (connection will go SG->AU->USA for cross realm and you will lag even more if you don't use setting)
You can change it back to normal with the Default Game Setting button.
