What is a LINK in a setlist? I haven't seen or noticed this before.

Just saw an option on a set list called "Link".  What is that?

Found the answer:

★ Added an option to visually link songs in a set list. On the set list's Edit Songs page, you can click Add a Link, then drag the link between two songs. Then those songs will appear with no border line and a small arrow between them when you view your set list. You can use this function to indicate medleys, or groups of songs that you want to perform with minimal gap between.
