Accessing a list in a different workspace

[Anonymous]

Hi,
I have set up a separate workspace (workspace2) for a partner to upload lists into and it works great.  However now what I want to do is be able to access that list (through a smart list) from another workspace (workspace1) to see if they have participated in any of our campaigns.
For example I want leads who are 

Member of program A (in workspace 1) and 'was added to list' = 'workspace 2 list'

What I am trying to accomplish is finding the overlap of leads.
Does this make sense?

Unfortunately you can't see assets across workspaces. Assuming both workspaces are linked to the same Lead Partition, you can use a field value to do this comparison (e.g. make sure they populate a unique lead source value).
