Pan Crop x2 Sony Vegas

[Compo]

I'm using Pan Crop to resize and reposition a still image so I can fit text above or beneath it. Fine.
Now then what if I wanted to leave the image the same size on the screen but animate a "pan" across the image for example.
I can’t use the Pan/crop to create the animation as this will spoil the size and position of the image that I have just set?
Is there a way I can animate (pan or zoom) my resized image?
Can I add a second keyframe to the same clip?
Is there a way? (apart from exporting the image and resizing and repositioning it in another program and reimporting etc etc (Tedious!!)
Thanks

Simply use the "Track Motion" tool.

What it does, gives it its name. It lets you slide the track around or put it into 2.5D motion. It's not really just a PIP tool.
