Yes, would require a backflow shutoff valve and a bit of plumbing. Surprised that AC installers haven't suggested this method ...but, agree that the monthly manual flush works just fine!

The easiest way to accomplish what you suggest is to buy one of these from Amazon.

It just connects to a garden hose and no backflow preventer is needed. I have one and it works well, but you do need a second person to make sure the device stays inside the pipe.
