How to Stretch and Compress an Image at Specific Angles in InDesign

I always try to include a graphic illustrating my issue, so...

My goal is to stretch and compress the same image where indicated.

The stretch parts are easy:

1. Highlight the image.
2. Go to Properties.
3. With the proportional Horizontal and Vertical percentages linked, adjust the percentage of either vector as necessary.
4. Unclick image.
5. Save.

Now, the issue is that I also want to compress the image where indicated. The area where I want to use the image has lots of space on the horizontal and vertical edges, but at the 45° angle, not so much space.

Another way of putting it: Stretch the ends, pinch the center.

Can this be done in ID? If so, how?
