Breakout room Activity centers

Hello, 

I work for a company that does online training.  We are trying to convert In person workshop to a virtual workshop. For the In Person workshop, students are broken into groups they have to complete an activity at one station. Then after some time they switch to the next activity.

Is there a way to pre-load activities i.e. videos, PowerPoint, documents, etc. into breakout rooms?  Then once students switch to a different breakout room the items are waiting for them.  When I go into breakout rooms as a host and add a whiteboard or share a video and then leave the room those items disappear from the breakout room. If not is there a suggestion on how we can do this using zoom?
