Custom Legend Flow Setting?

[AcornEnvironmental]

I'm having trouble adjusting a legend to automatically flow symbology to a new line if its longer than the set width.  Is this possible?  See screenshot for example on how it's cut off.  There are 10 more symbols that are cut off and need to drop below the first line.

Thank you for the tip.  This does not appear to work.  Bummer, was really hoping there was a way to automate the legend other than embedding it as graphics.

Make an Idea for it.
