The tpl parameter to many NATS and CARMA functions lets you change which template the function uses to display its output. For example, the NATS4 template function, nats_display_adtools, normally displays its output using the function_display_adtools template. In the Skins & Templates Admin, you can duplicate this template, edit the duplicate to change its format slightly, and then use the duplicate with the following code: (Note: the duplicated template is named function_display_adtools2.)
{nats_display_adtools tpl="function_display_adtools2"}
