There are probably a couple ways to handle this. Is it possible to get a flag into your load which identifies the most recent load?
You could probably do it with a macro. I'm not sure how your timestamp field looks. Are all of the timestamps for the most recent QVD the same? If so, you should be able to use the expression: =MAX(TIMESTAMP) to get the greatest number (this assumes all of the QVDs are linked up). It's may be easiest to set a variable (vMaxTimeStamp) to this expression.
Then you can set up a macro which uses: ActiveDocument.Fields("TIMESTAMP").Select $(#vMaxTimeStamp)
If you put that macro in your OnOpen, it should happen as soon as the document is opened.
Depending on how your data looks and what you're working with, you'll probably need to tweak this a bit.
