Windows 7 servicing stack updates: managing change and appreciating cumulative updates

I, DrPCDr.ca, deploy images of Windows. I also service Windows deployed years ago. I need to keep my images up to date. Also need an easy way to update old deployed images. Many PC techs deploy Windows from scratch. Therefore such a deployment of Windows 7 would require a lengthy messy online update procedure. The convenience rollup for Windows 7 SP1 can install offline all updates, February 22, 2011 through April 12, 2016. This is convenient, saving EONS of time! Life hacker has a great tutorial here: https://www.lifewire.com/latest-windows-service-packs-updates-2624595 Now is there an easy way to update Windows 7 from April 13, 2016 to present (March 10, 2019)? Microsoft should create patches which install all updates from the previous patches. Quarterly convenience updates would be generated each year. These updates would be cumulative including all previous updates. These updates will be smart enough to install only updates not already present or in need of repair.
