Currently, sesh has an option for scheduling monthly events on the last week of the month. However, this can vary--sometimes that is the 4th week, and other times the 5th. If I want to make an event that recurs on 5th Wednesdays of the month, I have to create a separate instance for each 5th Wednesday of the year, and remember to create them individually for subsequent years. This is not ideal. 5th week of the month events generally work out to be quarterly. My community likes to use 5th week for events that don't need to be monthly but should still occur more than annually. Adding this option to monthly recurring events (without removing the existing last week functionality, so those who make use of this can keep doing so) would be much appreciated.
