Have you rigged a "manifold" system to water 2 or more rows in multiples of 2. I did that several years ago with our 3 front beds. I could water 1, 2 or all in any order depending on where it was needed.
I have manifolds for my rows in the gardens and the greenhouse. Inch and a half poly pipe with (about) 6 or 7 hose bibs and then soaker hoses. The soaker hoses are my weak spot because they don't last all that long.
