Setting student level, grade and course on the group!

I have a number of groups (classes) set up and I have created activities within each. A massive and annoying problem I’m facing is that once I’m in the group and I want to setup a new activity I have to prompt with grade level/course details of the students. Surely it makes more sense for this to be at group level, then every activity within the group already knows the group and target level.

This will make it very intuitive, I have feedback from many teachers about this and its making it difficult to use!
