Slide template objects skewed when project dimensions are changed

We have a new SL2 format at our work that has a story size set as 966 x 533.  Because this is a "widescreen" format it skews the slide template objects such as the tabs in the Process Interaction slide template and the Tabs Interaction slide template.  Upon investigation, the reason for this is that the objects within the various states were shifted when the story size was changed from the default of 720 x 540 to the new company template size of 966 x 533.  It is VERY labor intensive to align all the states for multiple tabs.  Is there a way to change the story size without jacking the templates or, even better, is there a way we can make our new company format size (that we are required to use) have the correct settings automatically for the new format size?  We would rather have the slide templates automatically be correct for the 966 x 533 size rather than having to fix it every time we create a new project.
