Build/Buy a real CI/CD system for this TBH. Once you hit a certain level of complexity, this sort of deployment strategy will mostly just amplify pain.
I hate to be a downer, but ultimately the people doing the planning and allocating budgets at non-tech companies do not care about the nuances of workflows. They'll lay as much cognitive load on you as is allowed, and they'll always have another body to bring in if you end up quitting.
The value proposition here is clear: "This tool will make it harder for your engineers to do time theft. What used to be an hour's long effort of painstakingly hand-coding boilerplate as a way of 'taking a break' will now be at most 5 minutes worth of easy code review."
