Campaign Status sync for Leads

Campaign Status sync for Leads

Hi,

I am curious to why the 'Campaign Status' for Leads doesn't get updated like the one for Contacts, when we send out a certain newsletter to almost the same list every time?
Is it something we are doing wrong, is it a bug or it's not integrated? Though I guess it is, since there's the 'Campaign Status' field you can add to Leads.

Thanks,
Miruna
