If a team tells you they won't be playing the next round, mark them as not continuing in the standings. This keeps them out of the automatic import when you create the next round, without affecting their current round.
How to mark a team as not continuing
Go to the finished round's Standings
Find the team and click the "..." menu on their row
Select "Won't continue next round"
That's it — no confirmation needed. The team keeps playing out their current round; only the next round's import is affected.
What happens next
When you create the next round and use "Import teams from previous round", the team is listed under "Not continuing next round" and is skipped automatically
Their spot stays open — you can fill it from the waiting queue, or by dragging teams into place after import
Changed your mind?
Click the "..." menu on the team again and select "Include in next round" to undo it.
