We have the system setup so that the Webmaster (me) does the reviewed and runs a pre-publish at 5:00 p.m. Monday - Friday. The full publish happens at Midnight (7 days a week).
Image assets and web pages can be giving a date/time stamp to publish and I use this to swap out my own banners.
However, there is a department that often needs their banner images and banner links changed by Monday. Because the banner is linked - it would mean the HTML Asset would also need to be changed.
Is there any work around to this I might be missing?
