I am using the IMAQ Select Annulus ROI VI. I would like the image that is wired to the VI to be displayed in a "Zoom to Fit" format in the modal window that comes up to allow the user to select the annulus. Currently it comes up zoomed in at a very large size (likely full size) and has to be zoomed out manually each time in order to select the correct annulus. I have dug into a couple layers of the IMAQ select annulus VI to the IMAQ Construct ROI but can't see a good place to plug in the Image Control property node "Zoom to Fit Mode" to get the image to display correctly. In fact, I'm not able to see how the front panel of the modal window is constructed at all and am not sure how the Call Library Function Node works on the block diagram. Is there any way I can get this image to fit to the modal window so the user can save some mouse clicks?

Thanks Jacob, will pursue the workaround in the event I need to pursue this route,
