Can I train my pinkie to move independently?

Have you ever noticed when you hold your hand out flat and try to curl your pinkie down to your palm your ring finger moves along with it? Is there any way to train your pinkie to move independently? Im not sure the medical reason for why this happens.. connective tissue, adjacent ligaments or tendons maybe.. but i feel like i could benefit from the ability to move it by itself for various music related endeavors. Any knowledge on this topic, tips or tricks??
