I want to know this too. I have tried doing the same thing and just gave up.
At our company we insert new one row tables and just line up the top one to the bottom one so it looks like a milti-row rev block. It's a pretty dumb way to do it, but it's easier than resetting all of the text settings for a new line. I waste a lot of time zooming all of the way in to click really close to get the tables to look like they line up. (Why isn't there a snap feature for table points?)
Anyways, if someone has a fix for this I would be grateful too.
