Open the slide options screen, and click on Effects tab. Along the left edge you will see an icon that looks like two baseball home plates, if you hover over it will say Copy Motion Effects. Click on the icon and you will have variety of copying options, including copying the end of the current slide to the next slide. Be sure to select the appropriate layer, or choose All Layers if you want the entire slide copied over. This will copy the ending position of the current slide to the following slide. I often use this technique to add a 1/2 second "freeze" slide (0 transition time between) to freeze the motion effect so that it doesn't transition too quickly to the next slide.
Hope this is what you were looking for.
