Making thumbnails default on

I am needing to make the thumbnails appear when opening a PDF file.
 
I am familiar with the Batch Processing function, but can make it work on existing PDF files only. The problem is that we work with new PDF files constantly and need the thumbnails to open automatically when choosing a new PDF file. I have attmepted to set the Run commands on: Files Open in Acrobat. This seems logical, but it does not open the thumbnails when opening a new PDF file. The only ones that open are the ones that are batch processed.
 
Is it possible to make Acrobat Pro automatically have thubnails to default on when opening all PDF files, including the new ones, without having to batch process a folder of files on a regular basis?
 
Thanks,
John
