Hi, I use the app for a swim team, and we will have groups of swimmers separated by lanes. The swimmers do a staggered start of 5 seconds apart. Is it possible to have multiple columns, and have a staggered start within each column? For example, first person in lanes a/b/c will start together, and the 2nd person in lanes a/b/c will be staggered 5 seconds after, and so on.

Thank you and loving the app.
