[v11] DatePicker: Range selection with Time component should have configurable start/end target

[jakkn-sk]

When using

<DatePicker.Root
  selectionMode="range"
  showTime
  hourFormat="24"
  stepMinute={15}
>
  <DatePicker.Input />
  <DatePicker.Portal>
    </DatePicker.Container>
   [...]
    </DatePicker.Container>
      <DatePicker.Time dateIndex={0}>
        <DatePicker.Picker type="hour">
          <DatePicker.Increment />
          <DatePicker.Hour />
          <DatePicker.Decrement />
        </DatePicker.Picker>
        <DatePicker.SeparatorContainer>
          <DatePicker.Separator />
        </DatePicker.SeparatorContainer>
        <DatePicker.Picker type="minute">
          <DatePicker.Increment />
          <DatePicker.Minute />
          <DatePicker.Decrement />
        </DatePicker.Picker>
      </DatePicker.Time>
  </DatePicker.Portal>
</DatePicker.Root>

that includes a Time component like this

there is no way to direct the focusedDateIndex. It defaults to the end date, but I want it to target the start.

I put in dateIndex={0} in the example code to illustrate what I'm trying to achieve, but it doesn't work of course since it's made up.

If this is in fact supported and I'm just doing it wrong, please enlighten me :)
