Probably your best bet is to use ActiveX and control Word from LabVIEW, this way, you can act as you were using Word directly, automating all the steps to create your report. Look for examples in the developer zone, although there will be more examples relating Excel, that can show you the way to act. If you need to use this intensively, i think NI has created a Word toolokit that you can buy.
For any particular question, just ask.
Good luck
