ZoomEvents for conferences

I am trying to use ZOOMEvents to build a conference platform.  The structure I need  is something like this

Main page for 3 day conference 

        Three events for the three days

               a number of sessions each day ( no need forconcurrency at the moment)

                          within each session a number of speakers  (say items) one after the other  

Also I need to attach speaker bio, prerecorded presentation and a pdf copy of the paper.

Also I could not add hosts for each session.

Any advise would be most helpful.
