While we import your league rosters and settings, we currently do not support integrating directly with online drafts, as they progress on your league site.
Entering picks though is super easy. From the draft board list of picks in the app, hit any pick at any time and then hit the player selected. The app will automatically then navigate to the next pick. Most picked players will be in the top ADP players remaining, so immediately visible and clickable; those that aren't are easy to find either by searching their name or filtering by position.
It's also super easy to correct any mistakes by either swapping players or inserting players if you missed one. Check out this article for more detail: Fixing Live Draft Mistakes
