hello! Is there a way to add say 200 mock patients to our dev project that wouldn't involve manually constructing 200 unique patient objects and uploading them?

Hi @stefant1707 - have you checked out the Synthea project? It's maintained by a group called MITRE, and they can generate FHIR data under ssome configurations https://synthetichealth.github.io/synthea/

I haven't, thank you this looks helpful!
