Thanks, Rick!
Your info was very helpful. I did consult the list of “monitorable” events and deleting an anchor is not on the list. But, it’s good to see what is available for future projects.
I was trying to prevent deleting of a single anchor, but instead I’ll move on to the next component of comparing all the anchors to a .csv file. I know I’ve seen posts about this before. So, I’m off on another fact finding mission. 
Thanks again,
Heather A
