Applying 'overshoot' to keyframes

Is there any easy way of applying overshoot to keyframes? I had a look at the expression modifier but will likely need a bit a guidance - it’ll only need to overshoot once, and will not be animated further.

To put it into context I’ll be using it for pins popping up on a map, but at the moment they don’t quite look right as they lack a bit of overshoot/bounce.

Side note: It would be quite nice to have an option to stagger layers in the timeline (similar to ae) :slight_smile:
