How to schedule recurring race in Garmin calendar / Garmin Connect?

I run with a ParkRun community in my home city. As some may know, it is a weekly volunteer organised free event which happens every Saturday in open spaces worldwide. We would like to set-up a recurring race in Garmin calendar / Garmin Connect, so that foks looking for events through Garmin search can find it.

Question is how do I do it? I can set up a scheduled event for a specific date, but I need to repeat it for every event. I hope there is a better way. Many thanks.
