How to batch add folders to Folder Actions

I actively manage a directory of folders that contain images that are organised by modification dates. Due to this, I had made a quick action that used an applescript and bash to help me ensure that newly added files had the right modification date. This was time consuming, and eventually I learned that I could set up Folder Actions that could automatically do that work for me. I did so, and now I face the struggle of adding multiple (lots of) folders to the Folder Actions Setup window. In the spirit of automating everything, is there a way to add Folders to the Folder Actions Setup window and all added folders to have my folder action enabled? Not sure where to start! There was an [app](https://www.macupdate.com/app/mac/24010/batch-apply-folder-actions) made for this, unfortunately the download link no longer works and the developer has removed it from his page of projects.
