You may need to make adjustments to lane assignments beyond the initial sorting or re-seeding from leaderboard.

To do this, select "Lane Assignments" from the Scheduling menu, and select the division(s) and workout(s) you need to adjust. Then select "Update manually," circled in red in the screenshot below.

All athletes have a rank associated to them which correlates with their lane and heat assignment. Simply type a new number to swap an athlete.

Once you are done editing, select "Done editing".

Once you are done making manual adjustments to lane assignments, proceed to "Review and Publish" in the scheduling menu and publish your heat schedule.
