I was personally planning to have a kid in the stands with a big sign they waved if there was a ball under the bridge. That was a pretty common practice in Breakaway (2010) to let the drive teams know that there were balls available up against the driver station wall right in front of them that they were unable to see.

If they formalize it, fine, if not, there'll be lots of teams with someone on the sideline or in the stands giving hand signals.
