No document types for Leads in SAP C4C

Hi Experts,

I am using SAP C4C 1605 version system and i can't see any document types for 'LEADS' especially to configure a new lead type as per client's requirement.

Is still SAP is working on this functionality for leads, where i can see document types are available for remaining business transactions. Anyone please let me know any updates on this?.

Many Thanks,
