User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:10.0.5) Gecko/20100101 Firefox/10.0.5 Iceweasel/10.0.5 Build ID: 20120629080115 Steps to reproduce: I want to schedule a meeting on the 1st, 3rd and 5th Monday of the month. In the Repeat dialog I can chose a Custom schedule, with a recurrence pattern of Monthly, choosing the 1st Monday of the month. Actual results: The meeting was scheduled for the 1st Monday of the month Expected results: I should be able to select multiple custom repeating schedules. For this particular meeting, I should be able to add another repetition for the 3rd Monday of the month, and then another for the 5th Monday of the month. I can work around this by creating three separate events, each with their own customized recurring schedule, but that is awkward (and perhaps not obvious to people).
