Flipgrid and Multiple Sections in a Course

Community Novice

I teach 3 different classes across 5 periods and I would like to use Flipgrid in each period.  How do I integrate it in a way that will allow me to create a Grid for each period? I don't want my APUSH, US History and History in Film Courses intermingling their boards I would also like them to be separated by sections.  Can I do this? If so how? 

Also if I can not separate them on the grids by sections, I should be able to see their uploaded assignments in the proper gradebook right? Can I see and grade their video straight from speed grader?
