positioning element of a screenshot on a slide

[Kerike]

Hi everyone,

I try to make it simple. I pasted a screenshot into a ppt slide. That screenshot has a black background with two white dots. On the next slide, I have almost the same screenshot but the 2 white dots are in a slight different position. When I am moving slide to slide, I would like to have the 2 white dots at the exact same position on each slide. That way, the person see always the same reference slide after slide and he is not confuse by the different sizes of the screenshots. I used to do it manually by re positioning and re sizing each screenshot but it is very long and inaccurate.
Obviously, I can have up to 4 white dots on the first screenshot to match with the second, third... screenshot.


If you have knowledge in spatial data, it is like georeferencing an image but using the slide pixels instead of coordinates.
