Cross-Referencing CRM Solutions – Does It Exist?

Hello everyone,

Does anyone know of a CRM solution that does automatic cross-referencing between records? Initially I'm dreaming of a CRM solution that lets us input large amounts of data, and have the system make automatic connections between records. For example

Record A: Old client. Previously entered the name of a board member as a stakeholder

Record B: New lead. New input of stakeholders. This lead has the same stakeholder as our past client.

System: Automatically identify and notify us that Records A and B have the same information; but could potentially notify us of the same data regardless of field.

I've not been able to find a CRM solution that will do this. Is it too complicated or resource intensive?

Thoughts?

Thank you very much.
