Suggestion re Preso

I use Preso to create quick training videos for my students. I upload the Preso videos to facebook and my students have a tutorial within a few minutes, in answer to their questions. 

I can't understand why Preso isn't in the list of products? It seems to be there just to allow people to do reviews? It's confusing to me. 

I would LOVE to be able to share to social media, rather than use the review link which doesn't work for my purposes. To do that I need an appropriate way to link, and to create a short description and a thumbnail. At the moment it shows up as per the attached image, which is not very satisfying. I have to go to my computer, download it and then upload to facebook.
