Identify Dupes Between Specific Partitions
We have multiple different lead partitions for our multiple business units that like to cross-market to each other. I'm trying to figure out a way to identify the duplicates that exist on specific partitions so we can easily exclude those email addresses from our cross-promotion. I have a Workspace with visibility into all of our Workspaces so I'm able to set up a Smart List that identifies duplicate email addresses that exist in all partitions, but I'm not sure how to narrow it down to only identify duplicates that exist in both Partition 1 and Partition 3. So even if Partition 1 has duplicates with Partition 2, they won't show up in my Smart List.
Is this possible to identify in Marketo as a targetable Smart List?
