Charlie, Thank you for this awesomely complete and generous reply with images. What an amazing help you are. At first I found it confusing and then it started to make sense and now I am very excited to do this later today. I was so stuck not understanding why I was having trouble. I was following exactly the PG video instructions on this topic, but you have revealed some of the mysterious (to me) inner workings and quirks of this amazing but uber-complicated program. Anyway I just couldn't wait to thank you and will dive in and perhaps have some followup questions. This splitter feature is turning into an amazing tool for my practice needs. Onward and I will report back!
