Is it possible to have default dateTimeFormats?

When a dateTimeFormat is not found for the active locale it will search in the fallback locale. In this case it will show the date in the fallback locale format. Is it possible to use only the options from fallback but use the current locale.
Ex.

dateTimeFormat: {
    en: {
        short: {
            year: 'numeric',
            month: '2-digit',
            day: '2-digit'
        }
    }
}

If the current locale is en-GB, writing $d('short', date) will give a date like mm/dd/yyyy. Is it possible to use only the options in the fallback and the selected locale en-GB (of curse without passing everywhere the current locale to $d('short', date, currentLocale))?

I know this message is quite old, but did you found a solution?

not as a fallbak but you can copy the same config for all the locales

const timeFormats = {
    date: { year: 'numeric', month: '2-digit', day: '2-digit' },
    dateTime: {
        year: 'numeric',
        month: '2-digit',
        day: '2-digit',
        hour: '2-digit',
        minute: '2-digit',
    },
    time: { hour: '2-digit', minute: '2-digit' },
} as const;

// used it when creating vue-i18n
createI18n({
    // .....
    datetimeFormats: {
        en: timeFormats,
        de: timeFormats,
        nl: timeFormats,
    },
})
