Export to 5.1 doesn't works, QT ProRes422LT MultiChannel audio

[Zdenek22926292z2fb]

Hello, I'm using Premiere Pro and I've noticed, that when I want to encode MultiChannel Audio in QuickTime Apple ProRes 422LT I'm not able to export any 5.1 audio only 6 channel audio, please fix it. And maybe is also a time to support 7.1 audio in Your Creative Cloud (Premiere Pro, Audition and Encoder) which is started to be very common. Thank You. Best Regards Zdenek Jermar
