Can Global Context values be used in the content of a PX Engagement?

1. Global Context exists in the available data for engagements, as it can be used for Audience rules, etc. 
2. Engagements can show content to users(s) via a Guide, Dialog, etc.

Is there a way to use values from #1 in #2? 

Use case Example: 

Dynamic “Approver” value shown to users. 

1. Approver value exists in the Global Context
2. Engagement tied to a specific UI element (ex. disabled button)
   • Content: “This capability is limited to designated approvers only. Reach out to {Global Context Approver Value}”

In this example use case, the global context for the approver value would be unique to each customer company / product subscription. Rather than needing to have bespoke engagements for each customer, we’d prefer to insert that value dynamically into on engagement for all/most users.
