I have some bpmn and yaml that I want to feed into a new blueprint. The yaml that describes the data model, includes enums that would ideally become picklists with local lookup values that represent those enums. That doesn't work, and indeed it doesn't seem possible to choose picklist as an option for property types in blueprint. The majority of the case type I'm looking to build out will be answering questions based on dropdowns or segmented radio buttons. Is this a known limitation?
