Adjustments to background image

When setting the background in Compositing in iStopMotion for Mac, is there a way to make
adjustments to the background image within iStopMotion? For example, I’d like to rezise it, or zoom in on a particular area.
How about changing/modifying it mid capture; capturing a couple minutes “wide shot” against the background image, then zoom in or crop to a different area for a close up, or switch to a new image altogether?

Thank you
