Running into a problem setting up workspaces and partitions. I imported a list and found that a few of the leads being imported into one workspace already existed in another workspace as a contact. Because it existed as a contact already in another workspace, Marketo automatically used assignment rules for the existing lead. What I need to happen is for Marketo to create a new lead in the partition I am importing the lead into. I need the leads in each workspace to be treated as a new lead even if they exist in another workspace. Anyone have any tips on how to resolve this?
