Can we get component only from specified SerializeField object?

For example:

private class AnimatorOnModelFilter : SceneRefFilter<Animator>
{
    public override bool IncludeSceneRef(Animator animator)
    {
        // Get the EnemyController component
        var enemy = animator.GetComponentInParent<EnemyController>();

        // Check if this animator is on the enemyModel
        return enemy != null && enemy.enemyModel != null && animator.gameObject == enemy.enemyModel.gameObject;
    }
}

[Header("Core Components")]
[SerializeField, Anywhere] protected Transform enemyModel;
[SerializeField, Child(filter: typeof(AnimatorOnModelFilter))] protected Animator _animator;

Essentially I want to do:

_animator = enemyModel.GetComponent<Animator>();

Is there any better or shorter way to achieve what I want?

Edit:
I think I'll just use OnValidate for such cases, as it's less verbose code.

It would be great if there was some way directly as an attribute.

I agree, this is a much needed feature and something I've run up against quite a few times now. I haven't had a chance to look into it (PRs welcome!) but it's something I'll certainly be looking at at some point.
