Canon MG4620 - Scan multiple pages to one file

I have a Canon MG4260 printer scanner.
How do I configure the setup so that when I scan a document with several pages, all the pages are in one file? At present, each page is saved as a separate file no matter how I try to change settings.
Thanks.

 

After you scan the first page, does it ask you if you want to scan another? If it does, as many times as you hit yes and keep scanning, it will put them in the same file.
