Multi-file Upload Form Without a Submit step

I've created a custom form that consists of a single FileUpload field that accepts multiple files. As files are dragged/uploaded, they get uploaded as temporary files, which is great. Now I'd like to remove the need for a submit button on the form - instead, I'd like for each of those files, as they are successfully uploaded and received (as temporary files), to be processed by a ProcessUploadedFile job that I have within the app. The end result being that this upload form behaves more like a "drop box" to drop files, and they get processed asynchronously. Is this possible? Are there events I can hook into in the background as each file is uploaded and stored successfully? Screenshot attached for context.
