Yes! If you already have 360 templates in your main account you can share them so your customers can access them when they use your white-label version of the platform.
Once you have a 360 campaign you wish to template, click the arrow on the blue Edit button next to the campaign in the 360 Dashboard. Select the Create Template option and determine whether to publish the template to your account or account network.
To access your templates, select the Templates tab from the left-hand menu in the 360 Dashboard, which will take you to a page where you will be able to see all templates you have access to.
