I would like the ability to preview new and edited Advertising Campaigns before putting them live. We use this feature for areas like our homepage banners, and it is not ideal having to put our new banner images live in order to see what they look like on the actual homepage, especially if they don't look right the first time. To be clear, the preview would be most useful if I could see the entire web page housing the new/edited advertising campaign (not just the area of the template housing the advertising campaign image).
