LeanData Lookup Field into Marketo

Hi All,

Our tech stack is: Marketo integrated with SFDC, using LeanData for routing.

To route effectively, LeanData attempts to identify any links between SFDC Leads and SFDC Accounts and where it finds a connection, it creates a Lookup Field against the Lead, which would allow us to segment all leads that belong to Customer accounts for example.

The question is how to enable such a link into Marketo?  Currently we can only filter in Marketo on customer contacts, but I'd like to get Customer leads added to this.

Thanks in advance for your thoughts.
