Feature Request PlayerInput OnBindingChanged Callback

I'm updating my key rebinding system by using the rebinding example supplied in the Input samples.

This works to an extent but I have a local co-op game, so I'm using the PlayerInput components.

First I tried to add player separated logic to the RebindActionUI script in the sample, but it's quite the hassle.

Then I noticed that playerInput has a onControlsChanged callback which I'm trying to work with now which might work better, but this is more of a global "something changed" event. So this would update everything that plugs in to it, even tho it wasn't necessarily changed.

Isn't there some kind of onInputActionBindingChanged event in playerInput where I can just compare the assigned InputAction with the input action that changed and update only that UI accordingly.
