is there a 'before the create button is clicked hook'

It might not be a big issue, but I just discovered that in one have a upload comonemt in a form e.g. like this:

Forms\Components\FileUpload::make('thumbnail')
                    ->disk(config('filesystems.default'))
                    ->directory('articles')
                    ->visibility('public')
                    ->image()
                    ->imageEditor()
                    ->imageEditorAspectRatios([
                        '16:9',
                        '4:3',
                        '1:1',
                    ])
                    ->required(),

Forms\Components\FileUpload::make('thumbnail')
                    ->disk(config('filesystems.default'))
                    ->directory('articles')
                    ->visibility('public')
                    ->image()
                    ->imageEditor()
                    ->imageEditorAspectRatios([
                        '16:9',
                        '4:3',
                        '1:1',
                    ])
                    ->required(),

while this works it will give issues in some cases where the 'filesystems.default' is set to 'local' or if the the configuration does not have a 'url' key, in that case it would be nice to be able to do some validation even before allowing the user to create a new record.

I know that there is beforValidate() and beforCreate(), but in this case the user has already entered some information in the form

is there a way to do something just before the create button is pressed ?
