I am using Office 2000, and want to mail merge letters whereby the variable length addresses (i.e. addresses vary between 4 and 8 lines) have their last line at exactly the same vertical point in the letter.

I have tried using Powerpoint and Excel objects which both allow you to align text with the bottom of a box, but Merge does not function within either of these objects

The whole point of this is to be able to consistently produce letters which fold into window envelopes when folded on the mark our printer kindly put on our company headed paper!
