Question Can we control what field is automatically tracked?

Hi community,

let's say we have a monobehavior class A and a monobehavior class B. A has a serialized public float value_a.
Class B has a serialized float value_b and a reference to an instance of A (ref_a).

B is also marked with "ExecuteInEditMode".
Finally B has an update method which says:

ref_a.value_a = value_b;

Effectively that means when I change value_b in the editor, value_a on the other component is changed as well.

Now both components are in children of an animator.
When I record a clip and edit value_b, only a keyframe for value_b is added. Not for value_a.
How can I swap that?

Effectively I wish to record the effect of a script on component A and completely ignore what I manually do in component B.
Is this possible somehow?

Huge thanks in advance

P.s. of course the real usecase is a bit more meaningful than this.
