Is there any way to easily merge two rosters to put all students in one class, such as a team taught class?

I have four classes for my first hour: Essentials, On-level, 8th Graders, and Honors. I need to be able to see all of them at once. Instead, I have to view one of them at a time. We should be able to cross-list the sections.

I teach multiple grades at the same time, and it makes multiple rosters. I need to be able to combine these rosters... so they need to be combined!

Our students work independently online. I need to be able to monitor all 10 classes at the same time.

We should be able to combine classes. I'm a high school teacher who has several different sections within one class period, so I would like to view the entire class on one screen

I have several co-teach periods where my class is broken into two different sections. It would be helpful to merge these in Lightspeed so I can manage the entire class at once instead of having to switch back and forth between the two groups.

I just need to combine courses as most of my classes are "stacked" pre-ap and non pre-ap, I know, weird.
