Hey, just a quick idea I had pop in my mind - the ability to mass convert everyone in a group with a master program to a custom program.

Use case - if you have a group with a bunch of people who have cultivated community, and they were all on the same master program, you wouldn't want them to lose that sense of community by joining a different group if you needed to change some of the people to a different program, switch training plan dates, or have new members come into the group with their own start date for a program.
