Can a zoom webinar with a limit of 3000 attendees at a time host more than 10,000 unique attendees across its entire duration?

Essentially I am running a training program in which i have 10,000 attendees broken up into batches and different time slots.

A) Can I have a single link were i can call upto 3000 people at a time and then boot them out and have another batch come in on a same link?

B) Can I now have this as a recurring link where attendees can join across multiple days?

There will never be more that 3000 attendees at a time - though im hoping people can come and go.

It's a situation where person A using language a, and B language b are talking.

Audiences are using lanuage b, so they are in b translation channel.

A speaks then audiences can hear interpreter's languae b, after interpreting is over, and then B speaks.

When B speaks, audiences can't hear B's voice for about 7 to 8 seconds.

Is there a solution?

I keep trying to figure if this is possible. I want to end my webinar broadcast without ending it for panelists. Is there a way to end the webinar JUST for attendees while allowing panelists to stay on? It would be great to do debriefs after an event without having to jump to an entirely new meeting. Is this possible?
