No, I can't see that they do. There are two pages with relevant reports:
Sales Results lists two reports after each auction. One is the list of properties that went to auction and the other is the list of continuances. Looks like most properties that are continued are only continued for one week.
Sales Bids shows the bids for the upcoming or previous sale (Sales Bids) and the list of properties for the upcoming auction (Sales Report).
Comparing these, it looks like a majority of the scheduled properties actually get continued. I'm not sure when the new bids are put up. I've just not watched too closely. As of right now, about noon on Tuesday, last weeks bids are still up. The auction happens at 10:00 AM Thursday. So, sometime in the next 46 hours the new bids must be posted.
