It Is Possible To Code A Enemy's Advantage BGM?

Question

Hi P3P Modders, I've Been Wondering If Its Possible To Code In The Game A Battle Music That Play When The Enemy Attacks The MC Like In Persona 5 Royal, Where It Plays Last Surprise In Normal Situation And Take Over When The Enemy Ambushes The Party.I've Seen Mods Like Cutscenes Restored (PSP Version) And Field QoLs Change And Add Entire Features That Are Not In The Original Game And It Made Me Think What Features Could Be Added, And Since I Downloaded Persona Q2 Battle BGM I Have Wanted A Mod Like This To Hear A Different Music When The Enemy Ambushes The Party Because I Miss The Battle Themes So If Knowledge In P3P Modding Can Answer Me About My Question It Would Be Highly Appreciated By Me, I Hope Anyone With Experience In Modding This Game Answer Me So I Can Make A Request.Thanks If You Used Your Time To Read This, Even If You Are Not Going To Answer! <3Also Sorry If You Seen Any Grammatic Error In This Post, English Is Not My First Language.Thats It, Have A Nice Day!
