When doing a large irrigation system (I'm working on several with over 70 stations), the connection time is incredibly cumbersome and slow. The file I am currently working on takes up to 15 seconds to make one connection. Additionally, we have already turned off the Auto Calculation Update feature, so that is just processing time.   Some simple math to show you how cumbersome this actually is... 830 outlets of just one type (over 2000 total in the project) = 830 connections
