text in perspective

Hi all, I'm trying to manually write text in a two-vanishing point perspective in Illustrator CS4 without using th 3D effect Extrude and Bevel. I created a grid with two vanishing points for alignment purposes. Then I write some text that I want to transform based on the newly created grid (or guides if you wish) using the free transform tool. The problem is that I can move only one point at a time and then the bounding box is reset. What I would like to be able to do is to control the 4 anchors of the bounding box to project the text as disered (The 4 anchors should be located on the red dots of the image below). Is there a technique that can do that ? Thank you
