Show Number of Pages in pdfs when combining multiple documents

Acrobat 11 had a feature that showed the number of pages in each document being combined. Acrobat DC has it but you must hover over the document to see it.

We often need to view the pages to make sure that the pages are in even number and for quoting purposes. 

I used to be able to right click, combine files then view all the individual files pages but right now, its not showing anymore. 

Is there anyway that i can turn on such function again?
