How do I Import a pdf to a presentation?

When I import the PDF, it imports it into a 43 page Draw document. The import is a bit wonky, for instance, lines of text consist of a single vertical text element spanning the nearly entire page height for each character, but at least it is editable. However, I want to make a presentation out of this, and I have not been able to find any way to do this. The only suggestion I have found is to “copy” to Impress, but I’m not sure how this would work for 43 pages of mixed text and images.

edit: Ok, it appears that it really is as simple as copy and pasting, which really isn’t that simple for a large document, as it is necessary to copy the page, switch to the other document, paste, move the selection to tell it whether or not to adapt the objects (whatever that means), hit enter to do it, switch back to the other document, and repeat, for every single page in the document. Is there any easier way than this?
