Coloque o texto alinhado à direita na próxima linha se não houver espaço dentro de um \savebox

Question

Esta é uma continuação da minha pergunta anteriorColoque o texto alinhado à direita na próxima linha se não houver espaço. A diferença agora é que preciso colocar esse texto formatado dentro de um arquivo \savebox. No meu caso de uso real, por motivos de desempenho, estou armazenando em cache o texto que precisa seguir o texto existente (ou seja, na mesma linha), e esse texto armazenado em cache contém algum texto que deve ser alinhado à direita na borda da página.

Tentei usar todas as quatro soluções emColoque o texto alinhado à direita na próxima linha se não houver espaçojunto com um simples \hfill. Tudo isso parece funcionar quando usado fora do \savebox, mas não quando dentro do \savebox:

Notas:

• Eu possonãouso \parbox{\linewidth}{}porque não sei onde na linha começará \savebox. Ou seja, há texto na mesma linhaanteso \useboxé aplicado.
• A versão desejada teria o XXXalinhamento à direita assim como o ZZZtexto.
