Hi @aaron1, honouring of filters and actions performed by Readers when creating the schedule is currently not supported but is an active feature request as outlined in this Q&A thread. As a workaround you can leverage dynamic defaults as outlined in this blog post.
Let me know if this resolves your issue. Additionally, At AWS, our roadmap is primarily driven by our customers. Your feedback helps us build a better service. I have tagged this as a feature request.
