Good Morning. We are working on the CI pipeline for adding a pulumi preview check prior to merging a PR. It currently looks like when selecting --stack on the command line one is not able to do stack init automatically/ if the stack file is already committed to git? I was wondering if anyone had suggestions that work with a s3 backend

In our pipeline we get a list of all of the stack files, then check the names against the list of actual stacks. If it doesn’t exist, we init the stack, and then run the preview
