Email only faculty for current courses

When I need to hold a student from classes (or otherwise communicate with a student's teachers), I often use the "Email Faculty" link on the student profile. This has worked well. However, once students in the fall term have registered for spring courses, things change. When I click on that link, it emails the instructors in all of their unfinalized courses; i.e., all of their current instructors and all of their future instructors. Unless I modify the mailing list, I am emailing future instructors information that is irrelevant to them and is possibly a FERPA violation. Could you make the default behavior that the email list would only be faculty members for courses in terms which are currently in session?
