Alignment of a rotated Text!

If I rotate a text like:

<Text TextAlignment="Left" FontSize="20">
    <Rotation DegreesZ="90" />

It is posible to set the Alignment with the Text rotated? The text Align before rotate the text.

I need to show the rotated text in the TopLeft corner of the page. It is posible?

What does that code look like visually now?
