Portals occlusion fades in Open/Close

Question

Engine:Unreal Engine 4.18.3
Wwise SDK: 2017.2.4.6590

Good evening, I would like to see the following function implemented in Unreal Engine 4.

I have an AkPortal between two AkSpatialAudio. When I open/close the portal, all the sounds in the adjacent room appear or disappear immediately, relative to the Occlusion/Obstruction curve. It seems like the occlusion percentage goes from 0 to 100 immediately. Is it possible to have a fade value between them?
 Thanks in advance

Hello. Have you found solution to this problem? I am stuck with this also..

I am also looking for a solution to this. Would be great if the audio could fade between the open and closed state.
