I would like to use a Mandatory Building Block in 2 different landing zones. The problem is a value, e.g. a folder ID in which the projects (tenants) are located, would change. The only option would be to create the definition twice and support it twice instead of overwriting certain values ​​in the landing zone config. We do this on normal platforms with the platform specific config. Iam not sure its similar to https://meshcloud.canny.io/feature-requests/p/free-form-building-block-inputs-on-platforms-and-landing-zones or not. I created a new feature because its obvious that the Platform Specific Config is missing!
