granularity prop type on DateField component doesn't allow "month"?

[DarkstarXDD]

Hello, i have a form input where the user is only needed to enter the month and year. By default the DateField component allows month, day and year. I thought i would be able to remove the date segment by setting the granularity prop to "month". So it will only be month and year. While this works and the date gets removed from the input, it seems the Granularity type only allows either one of these values 'day' | 'hour' | 'minute' | 'second'.

So my question is am i trying to use this DateField component in an abnormal way? Or is there any other way i can limit the inputs to only accept month and year and exclude the day?

<DateField granularity="month">
    <Label>{label}</Label>
    <DateInput>
        {(segment) => <DateSegment segment={segment}}
    </DateInput>
</DateField>
