You can also do the opposite, and choose what NOT to clean up. It works on most (all?) of the structure nodes. (Eg. Case structures, and loops.) Right click on the the structure and click "Exclude from diagram cleanup." From now on, when you use the Diagram clean up on the whole VI, this node, and everything inside no longer gets "scrambled."

Between the exclude from clean up feature, and the clean up selection feature, the clean up block diagram function becomes actually handy. (No longer just called the VI scrambler.)
