Well let's look at what you say:
"I have the Document date field in the database set to Predefined as Modification date. "
"When I drag my files in to the folder it imports with todays date not the modification date."
"When I open the document and look at the bottom, the date is still the correct modification date, not todays date."
So, what is the question? You say you want the modification date, but then say you want todays' date
Sorry, but I do not understand this at all. It seems to me that it does what you want.
