Merge Join : Need no output match values (don't want to use lookup)

Hi,

I have a scenario where i need to get no match output values using merge join. I know usually we do that with lookup but i'm using third party data connector (salesforce connector) and can't use that connector in lookup (under "connection" as it only accept OLE DB Connection).

I'm wondering is there any workaround or I may use some other transformation to achieve this?

Thanks in advance.
