Instructor View: add a 'hold' option in addition to 'approve'

Originally, I wanted a 'hold' and 'delete' button here as we make assignments so that we can get rid of some of the noise as we 'approve' courses to be assigned to a particular instructor. Now I'm thinking we probably don't want a delete function because then you are modifying the original teaching preference of the instructor. However, I think a 'hold' button would be good. An example of using this option is that I have assigned 3 courses to a particular instructor and he's now teaching his full load. However, as we continue to assign instructors, sometimes we need to go back and modify what we originally 'approved'. So we want to continue to see what the instructor was willing to teach in addition to what we assigned him. I would like to put the courses not assigned to him, 'on hold' which would show in a different color than green or the text would show as strike thru or something. Also, this would help in the 'course' view, as you are assigning courses, I don't want to see instructor X on that course view if he now has a full load. It's fine to have instructor X continue to show but because I put that course on his preferences on hold, I now see his name striked thru or a different color. Again, we need to preserve the original preferences but be able to clear out some of the clutter to see who still needs to have courses assigned and which courses still need an instructor assigned. Hopefully this all makes sense??
