New Doc revision - not copy the file from old rev

@Mathias Dahl 

Do you know if there’s any control via Document Default Values to have the File option unchecked by default when we create a new Document revision?

The reason for this is that we implemented a CRIM to notify users when a certain document is about to expire. They would need to then create a new document revision and check-in the new PDF. So, we never will need to copy the old file in the new document revision. 

I see that this FileInfo parameter comes back as True in the API, but I couldn’t find any Document Default Value to control this.
