You can go to the tab "my account" and go to report. And, then, select a grouping.
However, what I do is, - I go to "domain names" tab and select "report".
It will list all of the names in that particular account at that particular moment.
I then copy and paste the list into an excel spreadsheet. And, work on the list from
within the spreadsheet.
I usually make a new file once a month for my records.
