Not that i know of. And i personally think it would be harder to get right. Though instead of clicking you can use z and x keys while hovering over joints to toggle extend/contract and hold/relax.
i think it would be a great idea if they do it so you can set limbs to drag where you want when you are setting things up, but there would be 2 problems.
1: hands couldn't move...
2: you could prolly drag the entire body up on accident.
