Option for automatic unmute during voiceover record

Hi, in this post Mr. Dan mentioned that he could make an option for an automatic unmute for those who use headphones for voiceovers. Can this be done? Would be a useful feature.
At the moment double click on speaker icon during voiceover record changes icon to “unmuted” but sound does not appear - even after record stops. I guess its a bug. For sound to appear volume slider has to be moved. ShotCut v. 22.10.25
