When managing your lists and campaigns, you may want to assign an existing list to a different campaign.  This way you can start fresh on your leads without having to purchase new ones.  

From the Dashboard, click on Call Center and select Lists from the drop down.

Click on the Action button and click on Edit from the drown options.

Under List Generals, next to Campaign click on the drop down arrow and select the Campaign you want the list to be assigned to.

Note: You need to deactivate the list first before the system allows you re-assign the list.

Scroll down and click on Apply Changes to save the settings.
