@joehanna thanks for the feedback, definitely understandable!
For now please use separate Bitrise.io accounts for these. You can just create a “machine/bot” account for these and invite that machine/bot user into the bitrise.io app. Then you can set for the app to use that machine/bot user’s Apple Dev Account (on the Team tab you can specify which user’s Apple Dev Account connection should be used).
If you have any questions just let us know!
