Once your league is created, we assign you a randomized schedule. Unfortunately, there is no ability at this time to randomize that any further at this time.
However, the commissioner has the power to update and customize the schedule using the 'Schedule Matchups' tool. This is available on both the web and the mobile app.
You can modify your league's entire schedule once your drafting is complete.
On the web, you can go to Settings -> Commissioner Control > Edit Schedule Matchups:
To do this on the mobile app, press the settings icon in the top right, then choose the Commish tab and then scroll down to the Schedule Matchups option.
