Sourcing Highlights from Multiple Projects in Insight Workshop

I'm working on a meta-project to synthesize highlights across 12 different projects spread across many many folders but ALL using the same global workspace tag groups. I created a new project called "Insight Workshop" and want all of the highlights from the 12 different projects to magically be available for synthesis in this new "Insight Workshop" project. I can't figure out how to reference highlights from other projects into an existing one. I must be thinking about this in the wrong way. Alternatively, I can go into each project and export the highlights into a CSV and import into Miro and do the synthesis there. Appreciate any suggestions.
