@webline—Thanks for this AppleScript. I am trying it out and working on integrating it into my workflow.
You have provided a nice bridge over a hole in Tinderbox. I was playing around with the “attribute” operator and its reputed ability to set at least the default and suggested configurations for attributes, but as has been noted by @mwra in the posting on List attribute options, this feature is not working, at least not with 9.1. Hopefully, your AppleScript will let me move forward.
