Concurrent Webinars - x1 500 webinar licence with several individual licences

Hi

We have two webinars due to be run at the same time on 29th March. We have 1 500 attendee webinar licence and several individual licences for hosts. 

Will we be able to run webinar 1 with host A and webinar 2 with host B at the same time? Also what would be the attendee capacity for each webinar - 500 per webinar or 500 across both events?

Thanks
