I was so thrilled to see your instructions so quickly, I didn't even read the last line regarding your automating this. That would be awesome!
I played around some with PS6, but if you do have the time to automate, would love to see how you do it. No rush. I'm going to work through the step by step instructions in the book and add in the above instructions to create the action on my own. I'm sure you have a much quicker way (like using the transparent_white portion of your action, and adding the above instructions). I thought about that, but don't want to infringe on any copyright violations.
