Can't find support for U807 with Combo test build

I loaded the combo test build to support my X9 and MJX X600 copters. But I have lost support for my U807 which flew through the FLYSKY protocol, but with the V6x6 extension. I am not seeing those extensions in the combo test build.

Am I not looking in the right place, or were they removed?

Thanks

Just to close this thread, I have found my answer through another site.
