Schoology Integration - Student Access

We recently moved to an integration with Schoology for our district subscription, but the only way for our students to access the program is through a course in Schoology that uses Noteflight.  Since some of our music courses are quarter or semester based, some students are losing access to the subscription once they are no longer enrolled in the course.

It would be great if we can figure out a way for students to access our website from our site URL instead of only through a Schoology course.
