Use SerializeField to play sound, for ScriptableObject

Hello.. I've bought this asset because it had some good things, but I ran in a big problem :
In my game, I use sound in my ScriptableObject, used with SerializeField to insert an AudioClip, and playing it, but my list is huge, can I play an sound with an AudioClip ? Because I don't want to have so many sounds in my MasterAudio prefab..

Here an example of my script1 :
public class ObjectBase : ScriptableObject

[SerializeField] AudioClip myAudioClip; //+ a property named "MyAudioClip" to access it.

and 2nd script :
I can Serialize a string with the AudioClip name to done that, but I've too many sound, I don't want to have a prefab with +100 sound, I'm new to this asset so, I think there is an easy solution.. If someone can help me please, thanks ^^

EDIT: Finally I've workarounded it with string SerializeField to find clip, now my prefab have more than 100 sounds yay I'm happy
public void PlayBlablaAnimation
{
AudioManager.instance.PlaySFX(ObjectBase.MyAudioClip, volume)
}
