I have created a number of plans with individual source repositories defined per-plan (not really realizing that shared repositories were an option). Realizing I needed to make a change to all of them, I assumed there was a better way... shared repositories. So, I created a shared repository that mirrored how I set up my source repositories. Then I went and tried to reconfigure my plans to use this new shared repository.... but I can't figure out how. Any ideas? Surely I don't have to re-create all my plans from scratch...
