Actions on the Mac currently has the ability to repeat an action on one day in a week each month, e.g., every 2nd Monday. I simply select the Repeat Every...and then the week number and day. However, I have bi-weekly events that repeat every 2nd AND 4th Monday. So I must create two identical actions that repeat a different week. Very inefficient and sometimes confusing. Actions would be sooooo much more convenient to both set up and view if they could repeat in two or more weeks each month: 1st and 3rd, 2nd and 4th, bi-weekly on Monday, etc.
