Well…you can either keyframe it by hand, or purchase a script which does the job:

You could also do it with expressions:

or paste the following code into your position expression (you can change the “5’s” in each parameter to change the effect’s behavior). Then animate two keyframes.
amorti = 5;
freq = 5;if (numKeys > 1 && freq != 0 ){
if (nearestKey(time).index == 1) { value }
else {if (length(velocity) == 0) {
tempsClefProx = nearestKey(time).time;
if ( tempsClefProx <= time ) { tempsDebut = tempsClefProx }
else { tempsDebut = key(nearestKey(time).index-1).time }temps = time - tempsDebut;
spring = velocityAtTime(tempsDebut-thisComp.frameDuration) * ( .15/freq * Math.sin(freq * temps * 2 * Math.PI) / Math.exp( temps * amorti ) );
valueAtTime(tempsDebut) + spring;
}
else { value }
}
}
else { value } -
How do I use expressions?///

You can download this preset which applies the expression automatically:
https://mattrunks.com/en/tutorials/after-effects/amortype
Be sure to watch the video tutorial first so you can see how it is used.
The expression above is from this preset, notice that the variable names are in French (eg: tempsDebut for start time), the language of its author Mathias Peresini aka Mattrunks.

You can alt click the stopwatch simbol in the selected property to enable them. You can then later save that animation as a preset so you can apply it like you would apply an effect…
keep in mind that the same code there works as well with scale.
