Non-Blocking Calls to Query namespace in Unity

Question

We are trying to make use of the Query API in our game without having the calling thread wait on the audio thread. The main function we would like to use is AK::SoundEngine::Query::GetRTPCValue(). We've seen this post (https://www.audiokinetic.com/qa/1/why-are-calls-to-the-ak-soundengine-query-namespace-blocking) which recommends registering a global callback with AK::SoundEngine::RegisterGlobalCallback() which will be invoked from the audio thread so no waiting is necessary. However, that function appears to be unsupported in the Unity Integration of Wwise (https://www.audiokinetic.com/library/edge/?source=Unity&id=pg_limitations.html).Without AK::SoundEngine::RegisterGlobalCallback() exposed, is there another way to make non-blocking calls to the Query namespace, specifically with the Unity integration?

I am having performance issues with Queries in the SDK. Whenever I call a Query function, my game ... a few milliseconds. Is there something I can do?
