In the help article (https://knowledgebase.constantcontact.com/email-digital-marketing/articles/KnowledgeBase/28143-Customize-What-Each-Contact-Sees-With-Dynamic-Content-Blocks-in-the-Third-Generation-Editor?_gl=1*1s842z0*_ga*YzY0M2JjMWItNTA1YS00ZGQ0LTljYjEtNmY3YzYwYzEwYTg1*_ga_14T5LGLSQ3*MTc0NTQ0ODY4MC4yLjEuMTc0NTQ0ODg2Mi4xMC4wLjA.&lang=en_US), it says "When adding a dynamic content block into your email, make sure to also add a default block which will be visible to those contacts who do not meet the criteria defined in the dynamic content blocks." I have a custom field. The data in the field is either: 1. Yes, 2. No, or 3. blank or null. If I add a dynamic block for custom field = Yes --- and --- a dynamic block for custom field = No, I can't have a default block for custom field = blank or null because it is automatically included in both the Yes and No versions of my campaign. AND, I can't set the dynamic block up to appear for custom field = blank or null. Is there a way to group the two dynamic blocks with a default block so that the default block knows to appear if the dynamic blocks don't appear?
