Cannot archive emails to bwc modules from Outlook plug-in for Sugar?

Hi,

When archiving emails from outlook, I can see all modules which have a relationship with activities/Emails, custom modules too.

But contracts modules (BWC module) is not visible. I have tried by creating a relationship with emails but still not visible.

I am using outlook plugin v2.1.0.

Is there any way to archive emails from outlook to bwc modules?

Thanks.
