Salesforce Account Hierarchy Intent Data

We use 6Sense w/SF CRM; we are experiencing an issue with deciphering intent data/surges. Our prospects and customers include many large health systems; we are integrated with Definitive Health for data integrity. In SalesForce there is a hierarchy of these accounts with the health system at the top level and the various hospitals/regions/clinics sub to the primary health system. Example: General Health is the health system, they have 19 hospitals in their hierarchy. General Health is the parent account and each of the 19 is a child account.

When we receive intent data currently only the parent/primary health system is identified. We were told by our 6Sense rep that there is no way to distinguish this if the email addresses of the leads/contacts/personas from the child accounts are all the same root. The email addresses are most often the same domain at the corporate level unfortunately.

This is really frustrating and renders the intelligence of a "surging" account close to meaningless. It requires a lot of manual effort to drill down and determine at the child account which hospital is actually surging and for what products.

I'm finding it hard to believe that there is no way to fix this with a product as sophisticated and expensive as 6Sense. Does anyone have tips to fix this? Greatly appreciate it.
