We do not have have a feature that allows to go to a specific location in a PDF/document file, or a way of connecting the call to action to go to that specific page or section of the file. The recommendation I was going to give, you listed it out, which would be to have these in separate parts, and then create a link to them.
If you think this would be a great idea to have implemented, feel free to log a product request in our Product Zone. We now give customers the ability to submit their own requests, and be able to track them. If you haven't already used this, you will be required to sign up.
