Currently, when defining an audience for engagements, the Global Context and Segment options are extremely limited. You can basically only do a simple match:

But I need logic similar to what is available for mapped features. For example, I’d like to be able to create audience criteria such as:

• iSegment A] was matched in last 30 days
• iSegment B] was NOT matched in last 30 days
• iSegment C] was matched 10 times
• iGlobal Context A] is sexample A] 10 number of times in last 30 days
• iGlobal Context B] is sexample B] 0 times ever (i.e. this user has never logged this global context)

The clearest example is to target engagements to users who have never used version X of a product, where ‘product version’ is logged as global context. I don’t think I can target an engagement that way with the current logic abilities.
