Batch updating urls in engagements, product mappers, etc

Related products: None

We need to update one of our products url. As a result any engagements and product mappers related to pages in this product need to be updated accordingly. Is there a way to define the top urls as global variables so they can be referenced when defining engagements and product mappers? 

Confirmed Gainsight has Host settings for Product Mapper which allows updating URLs in one go. We would need the same feature for engagements.
