IK Pinning the fingers to their position

Hello, I m really new to animation, what I want to do is move the hand

without moving or sliding the fingers, so that the palm lowers but the fingers don’t slide. Should I ik pin each finger to its location by using an ik constraint and set as targets dummy bones at their locations, there must be an easier way? Right???

Also any tutorial suggestions that go in depth on how to tackle this kind of problems will be really appreciated.
