Biweekly alarm added to recurring alarm option

Could you add more options for recurring alarms. I have appointments biweekly but we can only select odd/even weeks. Which goes out of balance eventually

I would also like to set repeats for individual weeks of the month similar to how it is in Outlook (ex. Occurs: every 4th week on Saturday). Even - odd is not enough, morning - night shift. Thank you very much.
