Currently, if you mass reenroll people for an ILC, you are not able to mass add them to a session. This is also true for individual reenrolls, where your only option is to go to their enrollments and Edit Activity.
When reenrolling people, it would be nice if a session pop-up showed for ILCs so we can reenroll into a specific session.
Thank you for implementing this. I don't know how to close this idea.
