There are a couple of options available to you for a solution. The first is to create two outputs for your form. One supplying the full results, as you have it now, and the other being the summary only. The advantages here are that this will be quick and easy for you to set up and that you can then send summary emails to those people who don't need (or want) to know the full details of a form submission. Depending on how often the 'higher ups' would refer to the detailed information may mean that this is not the best solution for you.
The other choice is to create a custom document for your PDFs. ProntoForms lets you create custom documents using DREL (Data Record Expression Language), Handelbars, or Freemarker. If you set up a custom document you have full control over what you display and in what order and format. The documentation on how to do this is all available in our product documentation here: https://docs.prontoforms.com/1374411/Content/Published/360000345463.html
The disadvantage to this solution is that it will take you more time to set up. You will need to add all the data and format the document yourself. Our Pro Services team can help you out here if you'd like of course.
I hope this helps, but if you have further questions or wish to talk through either of these options further, please let us know.
