Is it possible to set up repeating calendar events by day rather than date?

I attend several classic motorcycle shows and car shows locally. Some occur every first Wednesday of the month, some occur on the last Saturday of every month, and some are on the third Thursday of every month. Entering them every month is slow and I would like to see if there's a way of programming repeating events like this by the day of the week. Right now, if I select to repeat, let's say, a bike show that is coming up on Wednesday the 6th, I can't set it to occur every first Wednesday of the month, only on the 6th of every month, but of course, the first Wednesday of every month is not always the 6th of the month. I am hoping the fuzzy logic programming to do this is already here. (fingers crossed)
