Webinars - giving controls to a presenter

Hello!   As a host of the webinar, I want to be able to introduce the webinar, manage chat and QA, and all the other items.   AND - I want my Panelists - to be able to manage the slides when ready  (advance slides, share their screen if needed, etc...).

The only method I see for doing this is to Share my PPT; and give Access Controls of my mouse over to a Panelist.   There has to be a better way, right?     Isn't there a simple way to "give presentation controls" over a Presenter?   What am I doing wrong?   Thanks much!!!
