It would be a great feature in journey design, if read audience based journeys can be scheduled at different dates. Basically schedule follows a irregular pattern. Journey could be triggered on 11th of Jan, 17th of Feb, 25th of Mar, 15th of Apr and so on.
We understand one can use business events to trigger the journeys at different dates OR use a time condition journey. But it will be a cool feature to configure different dates in the journey.
