Automatic signal route optimization for Simulink?

I thought I saw some video recently for Simulink where you can have it automatically clean up the signal paths in a model. Is this something that is a feature in Simulink that I can make use of? I can't seem to find any options to reroute or optimize signal paths. Thanks

Select some blocks and signal lines, click the action icon "..." that shows up, and click "Auto-route Lines".

Oh perfect, thanks. I couldn't find this option in the File menu. I was looking all over.

Hello! Is it the only way? Can I do autorouting in old matlab version?
