I have a build
#10 deployed to production but need to quickly rollback to build #9 (the previous stable deployment). If I select the build #9 and click re-run it generates a build #11 which goes through test, staging, etc. This is problematic because the build artifacts are associated with build #9 and are actually readily stored & available in S3 in our case. A build #11 would a) take time and b) recreate the artifacts from scratch, thus, it would not be really a rollback.
Given how BB Deployments is built on top of BB Pipelines, I guess what would be needed is to be able to re-run a specific step.
