Hey @eldrizno - It’s great to see you back in the Community again!
Unfortunately, Inter-App Audio is not supported, so this will not work 
However, as @heysoundude suggested, we encourage you to submit these feature requests in our Suggestions section of the Community (which it looks like you’ve already done 
)
Regarding your question about AUv3 Plug-Ins, you are correct that AUv3 support is limited to the Master output.
I hope this information helps! Feel free to reach out here in the Community if you have further questions or suggestions, and have a great day!
