When I extend a student's enrollment, I have the opportunity to select any number of days by which to extend it, and this is nice as I charge my students a small fee for an extension of enrollment half the length of a standard enrollment period for the course. The problem occurs if the student pays me the fee after they have been unenrolled. In these cases I must manually re-enroll them. However, they are automatically re-enrolled for the normal enrolment period, even though I want it to be half that time. I would be helpful if the manual enrollment option allowed me to specify how long the student is to be enrolled. As it is, I have to go into the database everytime and change it.
