ZoomISO IFB (Interruptible foldback)

In a broadcast environment, has anyone figured out how to set up isolated communication channels with zoom participants? Example communicating with one presenter while another presenter is currently on air. At a previous facility we would accomplish this with one laptop per participant, with Dante for the audio and a Blackmagic Web Presenter to handle the participant's return video. We would like to use ZoomISO to handle the incoming presenters, but would need to be able to communicate with each presenter separately, so as to not disturb the person on air.
