How to make pdf pages artboards?

Question

Adobe Illustrator

Given: vector pdf, multipage.
What needs to be done is that in illustrator you can open not many times one page at a time, but open it once and all the pages would be artboards on one canvas. Is there a way to do it manually?

Answer 1

File -> open -> select pdf file
-> OK

Answer 2

This is a saved pdf without Private data if done in Illustrator. So only manually if there are no sources.
