Dynamically filter CPT

I back this issue.
I have several CPT’s and I need to dynamically display related content from a CPT or another. Exemple:
CPT’s: Organization, Event
Organizations: AAA, BBB, and so on
Events: Event A (organized by AAA), Event B (organized by BBB) and so on
Organization has a template in theme builder and needs to display the Events organized by it.

How can I do that? Query settings in Posts widgets are not dynamic. The Custom Fields plugin has shortcodes but are not allowed either.

Thought about creating a user for each organization that will be the author of each Event. Still, Query>author field is not dynamic.
