Instead of changing the same report over and over, you can actually create new reports for different listings underneath that partner. To do this, go to the home screen and hit the view all button next to your partner list. Then left click on the desired partner and then hit the Add Analysis button and a new one will be appended. This will create a blank analysis under the same partner so that you can use separate links for each report. If you create a new report, it will have its own unique link.
