Add a vertical SplitPane between the Steps panel and the panel(s) above it (Events and Crews / Manual Step Addition). This will allow the end user to choose how much of the upper panel(s) are visible.
Sometimes there are many crews assigned to a SWP, but due to the panel size and screen resolution, you may only see 2-3 records SDGE would like the user to be able to adjust the panels to see more crews when needed.
