Double role for interpreter

[MarcinHinz]

Hello,

In a few days I have a quite big event and I’d like to do it on Zoom Webinar.

The event will have multiple speakers that speaks few different languages. Whole event will be translated on 11 different languages.

Translation flow is a little bit complicated but I need help only with one thing.

If speaker speaks polish on stage there is a translator that will do polish -> chineese translation.
If speaker speaks chineese the same person will translate it from chineese to polish.

How to set this up on 1 translator account/laptop?

Can I give double role for this person?
