You can easily change your league's draft order settings from the league settings screen. From the Draft Wizard® "My Leagues" screen, click the blue "View" button next to the league you wish to change.
Next, click "Edit" under "Draft Details" as shown below. You'll then be able to manually update your league's draft order.
Please note that you will not be able to edit your league's draft order if you have opened the Draft Assistant. However, the option to edit the draft order will return once your Draft Assistant has been deleted.
