display name change by context

[kkweng]

I'm participating in a 3-month program that has on 3+ zoom calls per day.   During those we want to identify ourselves in groups by appending something to our display name, like "cohort 6".  That way when people are speaking we can understand what group they're in.   

But for all the other zoom meetings I do all week, I do not want that to be shown, it is confusing for my other clients.

It gets painful to rename myself 3x/day every day.   Also I have to *not* click links to enter meetings, and instead use "join meeting" and enter the number,   or else I don't get a chance to rename myself before it is visible to others.

Is there a way to have the context determine what is displayed, in a way I can control ?

Separately I have noticed that in some more formal meetings my display name is not used, and instead just first+last is shown.   That appears to be under the control of the host.

So perhaps there is something the host would need to do for this "context" choice to work.

If there was an efficient way to switch between accounts,  or to choose whether to be logged in on entry, those might be other ways it could work.
