You can pass a file with a launch command and record info but I like the idea of app URI. There are some examples here on the list. Also, if you do a send as record from the File Menu then you can see the format of the file.
Thanks for the Sunday reply, @Mark_Wonsil and @josecgomez ! I had searched a bit but didn’t see anything. Not sure how I missed the post you have provided but it certainly has what I need.
