If you experiment with that surname DNA report, you'll see you can set parameters to limit the display by vendor/type of test, and can sort the results by the person named in the profile, the date of their birth, and by the test taker's name...which can be really useful. Especially for common surnames, setting the parameters down to the vendor/test will be important to reduce the number of "hits." Each time you modify the criteria or sorting, you'll see a different URL in the browser address bar. You can then bookmark a particular report to go right back to it whenever you want.
