You can Recalculate to the cursor or maybe some other options could suit in different situations.
But that can take longer in some cases.
You can just roll the bone and point it where you need. The main thing I was “eye balling” was actually visualising with my mind all the palm bones bending slightly inward. I don’t want to overdo it because the hands would shrink as they collapsed together. So I’m imagining how much each bone should roll as I’m doing that. It’s not a centre convergence point but just a slight inward roll.
