Is there a way to avoid duplicate afterStateUpdated methods ?

I have code like:

                TextInput::make('number 1')
                    ->live()
                    ->afterStateUpdated(function (Get $get, Set $set): void {
                        $set('total', $get('number 1') + $get('number 2'));
                    })
                    ->numeric(),
                TextInput::make('number 2')
                    ->live()
                    ->afterStateUpdated(function (Get $get, Set $set): void {
                        $set('total', $get('number 1') + $get('number 2'));
                    })
                    ->numeric(),
                TextInput::make('total')
                    ->numeric(),

                TextInput::make('number 1')
                    ->live()
                    ->afterStateUpdated(function (Get $get, Set $set): void {
                        $set('total', $get('number 1') + $get('number 2'));
                    })
                    ->numeric(),
                TextInput::make('number 2')
                    ->live()
                    ->afterStateUpdated(function (Get $get, Set $set): void {
                        $set('total', $get('number 1') + $get('number 2'));
                    })
                    ->numeric(),
                TextInput::make('total')
                    ->numeric(),

Simplified example; but basically, one field depends on two others. You have to have the same duplicated afterStateUpdated callback on both fields.

It'd be a load nicer not to duplicate this and just have it attached to the total field. Is there a way to do this at all ? I've had a good dig but can't find anything.

(I realise I can extract the method to a closure/other method; but it'd still be nice not to attach it twice)
