Hey Wayne, welcome to the party! There are a lot of great folks here. Probably one the the best forums on the internet, period.
I did not pursue this so I can't answer for it. I was looking to KM to move files for me as updating to Catalina broke Hazel which was my go to for moving files. Not long after this question, Hazel was fixed for Catalina and I just went back to it.
I had the thought that I'd simplify my setup by using KM for all my filing needs and get rid of Hazel but Hazel is so easy and good that it doesn't make sense to reinvent that wheel using KM.
There are some coding wizards here that could probably do it using code to extend what KM has internally but I'm a coding baby and not interested enough to invest learning beyond my immediate needs tho I have poked at it a bit cause learning is so damn great too!
Hazel is excellent for moving files and has (like KM) a smallish learning curve to get it up and running.
Might I ask what you're looking to accomplish?
