Can I customize dynamic time format in WidgetKit?

As far as I understand, there are 5 nice types of Date style, and 3 of them supports continuously refresh.

If I want my timer a little bit different than the Text.DateStyle defined, what should I do?

For instance, default .timer shows 2:58, but I want a 00:02:58 to make sure it is aligned.
