Marauders Map showing at what you are learning

At the moment when a student is doing homework, it will say that they are at the class, for example "at Transfiguration classroom." This is pretty generic and I think it would be really cool to see what they are actually learning.

So for example, if a student is at the Transfiguration lesson where they learn the Wingardium Leviosa Charm that the Marauders Map would show:

Sebastian Hawthorne is "learning the Wingardium Leviosa charm"

There are different ways that this could be implemented, but one of the ways would be that the professor has the option to couple an "action" to their lesson in the admin class creation page. That way they could decide what would show on the Marauders map and a teacher wouldn't be limited in their curriculum at all.
