pre roll video ads on specific sections

In FLEX, pre roll video ads are only supported in the ROS position. This has created a problem for us with some sports packages we've sold for us in previous years. We have other non-sports videos on our sites, but we create a special advertisement with sponsors that runs specifically before state track highlights. So now, the pre-roll videos we've created for state track highlights are running on every video regardless of section/subject.

Would it be possible to create one of these options?:

• be able to assign pre-roll ads to specific pages (not just ROS)
• match ads with specific assets by using keywords or slugs

We use to be able to assign them to specific sections in ZEN
