Reference data from multiple events using Liquid

For example: 1. User triggers event A and enters workflow 1 (WF1). 2. Since entering workflow, user triggers other events (event B, event C) that have valuable information in them that is relevant for the user and you want to use in the content in WF1. Currently, you'd have to ensure event A has this, which it can't because event B and event C actually come after event A.
