Isnt there a query for all clients with estimated payments? Then you could click on the Last Modified Date column header to arrange them. I dont see a way to get the Accepted Date to be a column option, but I rarely use the Query, so maybe Im missing it.

Be forewarned, running a query can take a LONG time, may want to "set it and forget it" and let it run overnight, or at least go to lunch while it runs.
