Improve subject assignment in lesson creation

When creating and managing many lessons, perhaps all on the same subject, assigning subjects during lesson creation becomes less useful and user-friendly.

Possible solutions:

• When creating the course, a radio button or checkbox could be added with the words "Assign selected subjects to all lessons?" to create a cascading effect, avoiding the need to manually set the subjects for each lesson.

  With the ability to edit, add, or remove other subjects in individual lessons.
