Our current process for roadblocking a page is inefficient:

1. Setup roadblock ad slots in GAM
2. Create roadblock Drupal blocks for ads
3. Enable block visibility for roadblocked page; disable run-of-site ad blocks for roadblocked page
4. Undo Step 3 when roadblock has expired (non-automated)

There must be a better way to manage roadblocked pages from within GAM. Anybody out there have a better solution?
