Share course to a group feature

Hello, i’m very interested in this plugin, the pro version and app; but i have some main questions:
1. It is possible to create groups and sub groups and assign a group leader (instructor or teacher) that can manage the group?
2. If so, can this group leader share or assign a course to the group?
3. If so, can admins assign courses to a single group?
4. Can i as an admin or any instructor/teacher get reports from courses and quizzes? Like how many students enrolled, statics about quizzes, grades and such.
My main idea is to create an online community of learning where teachers can create courses and share it with their students in a “virtual classroom” using this tool.

Thanks in advance.
