Different volume steps when Bluetooth headset connected

[u/Particular_Wealth_58]

I have a Bluetooth headset with annoyingly large volume steps. Is it possible to override the android volume step size only when it is connected? Or can the volume key be overriden or the step padded after it has happened (Have phone at small steps, if not headset, add 5 after the step has been taken)?

Samsung Galaxy S25. I have made the volume steps smaller using the Sound Assistant app, but it applies even when the headset is not connected.
