Adding Animation

Hi there,

Is there a way to adjust the animation start point?

Let me explain, I am looking to have four boxes on my slide. When the user clicks on a box, text should slide out of it onto the page. The boxes are placed on the left edge so my text should fade from left to right out of the box.

Unfortunately, the only animations I have been able to find has the text sliding into place from outside the frame and over the box. 

I have provided a sample for clarification. 

Thank you
