not sure why this is being downvoted, but this seems like the best solution of all. it's still a one button operation but you're not locked in to pre-programmed choices and it can service the whole house (and office if you press it at work).
They really want to find a way to have me do exactly this. "Hey I need more detergent. Press skinner-box level. Great more detergent is on it's way! Right from your favorites list on Amazon."
And frankly, that would be great and wildly convenient.
