How can VIDEO_ON_DEMAND recommend a series instead of a video?

The data for my application is structured as Show -> [1..* ] Video. If it is a Movie there is one video for a Show, and if it is a series, there is a collection of Videos for that Show. My Item Interaction and Item data sets are all Video IDs as the ITEM_ID and in the Items Dataset I have added a SHOW_ID field.

When I'm generating recommendations, I dont want to recommend other episodes (Videos) of a Show, I want to recommend other Shows.

Any advice on how to achieve this? Do I need to structure my Datasets differently? Seems like this should be a core use case of a Video On Demand scenario, but it does not need to be handled. Do I need to develop some custom recipes? organize my data differently? somehow make use of filters?

Thanks for any advice.
