Hearing only originial audio in language interpretation

We use English > Spanish interpretation during our weekly webinars. Occasionally, we have English speaking hearing impaired listeners that would like to use the webinar so they can hear the audio better, but in the original audio which is English. Unfortunately, the feature "listen to original audio (language interpretation off)" doesn't mute the Spanish interpreter. I know that you can mute original audio and only listen in Spanish, but is there a way to mute the translator and only hear the original audio?  Thank you.
