Although I only work with individuals in one-on-one therapy, I use Quenza's group feature to organize clients by topic so I can efficiently send the same exercises to multiple people at once. For example, I have an "ADHD group" with 10 members. In Quenza Classic, when I added 2 new members to that group, I could retroactively add them to activities that had already been sent to the original 10 members—they'd receive the same exercise that was previously distributed. In Quenza Next Gen, that functionality doesn't exist. Now I have to manually send the activity to each new member individually, which completely defeats the purpose of using the group structure for efficient batch delivery.
