Would be nice to be able to set an instance wide jurisdiction on all created cloudflare OS resources

There doesn't seem to be a way to do this natively, my workaround has involved patching the fork which will obviously make it annoying to keep in sync with updates to the source long term.

Would be nice to be able to do this instance level

No file, test, or entry point is identified in the issue. Start by locating how cloudflare OS resources are created and how instance-level configuration is represented; done means one jurisdiction setting is consistently applied to all resources created by an instance without maintaining a fork.
