Set up a rule to send screenshots from photo library

Hi

Is there a way to set up a rule to send all screenshots from the Mac's photo library to a new folder under iCloud Drive please?

I can't seem to select the photos library to monitor.

TIA.

Photos' library is private application data and is not really something that is meant to be monitored. Is this your photostream? If so, maybe you can use something like IFTTT to monitor that.
