Opinion/Belief compass slides

Hello everyone, 

I wonder if anyone can help me with a small issue I am having. I am working with a slide based on the political compass to measure beliefs and attitudes, using a drag and drop template but without a drop target (they can place the notes anywhere). The outcome is not graded, but I would like to learner to be able to compare where they placed their notes on different slides side-by-side at the end of the process, so some way to record this arrangement is essential.

I think the most straightforward way to do this is to embed slides 1 & 2, say, in a 3rd slide in their final state. After the learner has made their selections 

I've attached some mock up images to show what I mean.

Any ideas or other examples i could learn from?

Thanks!
