CONNECT - leads on the app if duplicated or the same seller

We often find that one person owns two or three or four properties and it would be nice if we can have the ability in one contact to see those other properties meaning if I’m calling one seller who wants multiple properties in the app already I would like to see that connection so I can identify that for example 1141 Commerce Ave union NJ the same Seller also owns 1104 Liberty Avenue Union New Jersey Jersey if we can have a way to connect both leads so we can see it when we’re calling One that would be great
