Shouldn't be hard to make them call saveChanges instead of triggering an
upload.

You essentially need to do the same in the plugin:
obj.timer = window.setInterval("config.macros.upload.action();", [...]
becomes
obj.timer = window.setInterval("saveChanges();", [...]
Make sure you always have a verified backup when using this.
