Move and open file in one rule doesn't work reliably

Hi,
I am trying to sort pdf files from my download folder into different folders automatically but I also need to check their contents. When I add the two actions "Open in default application" and "Move to folder" this results in a few files being opened before they are moved but others are obviously being moved first so I get a "file not found" error.
Is there a better way to achieve this than adding a rule to each of the destination folders?
