Capo on 2nd fret on 1-5 leaving 6 string open. That gives an 'open D' sound. Clamp from underneath. There are 'open D' capos on the market, you clamp from the top and it has a cut out for the 6th string.
And it ain't just for strumming. I fingerpick all the time using capo all over the neck. It adds sound like barring can't AND you don't kill your wrist (especially if arthritic) with barring every chord.
