How do I allow a DH to start at my IF/OF/C flex position?

Here are the steps to add a DH to your flex position:

1. Go to League >> Settings >> Edit Roster Requirements >> Custom.
2. Click New Position and add the new position and set the minimum to 0, start to 0 and maximum to 10 (or some other large number).
3. Next, click the edit icon next to the flex position you want to change, and select the checkbox for the newly added position.
4. Finally, click OK and then save to complete the flow.
