Feature Request

Describe the solution you'd like

Changing specific field of model class (e.g. FlexMessage) is hard work for developer.

Adding lombok's @Builder(toBuilder = true) save us. (And optionally, @Wither is also useful)

Describe alternatives you've considered

    FlexMessage overWriteDirection(FlexMessage original) {
        Bubble originalBubble = (Bubble) original.getContents();

        FlexMessage modified = original
                .toBuilder()
                .contents(Bubble.builder()
                                .action(originalBubble.getAction())
                                .direction(FlexDirection.RTL)
                                .body(originalBubble.getBody())
                                .footer(originalBubble.getFooter())
                                .header(originalBubble.getHeader())
                                .hero(originalBubble.getHero())
                                .size(originalBubble.getSize())
                                .build())
                .build();
        
        return modified;

        // Result: Error because copying Bubble#style is missing... :sob:
    }
