Interpretation: mute original audio not possible!?

Update: This was the - unfortunately unsatisfying - answer from the offical Zoom support:

"We were able to confirm and test that even if an interpreter selected a different audio input the interpreter will still here the main audio. Unfortunately the mute original audio option is only available for participants and not an option for interpreters. We recommend for you to contact your account executive if you want to have this as a feature request."

Unfortunate. Especially because this problem just came with the last Zoom update, we never had it with the former version of Zoom. 

Unfortunately, this problem persists, and there seems to be little interest on Zoom's part in resolving it. As an interpreter, I find it incredibly frustrating that changes are being made to functionality, and it seems no one has actually asked a professional interpreter whether that particular feature would help or hinder us in doing our job. Yes, we need to hear the original when we work directly from what we call the floor. However, if we need to follow an interpreter on another channel (which then becomes the original for that interpreter), having the two audio feeds is chaos! What has possessed ZOOM developers? Why would it be less of an issue for the interpreter to hear two audio feeds at the same time than it is for a participant, who can in fact disable the function as it is deemed too distracting for them, and the Interpreter?? Is it not equally as distracting or even MORE so?

How can we impress upon ZOOM the need to reinstate that feature for the interpreters???? 

Suggestions anyone??
