No Link between Optimize for B2B and Optimize for Process ?

Its looks strange after I happen to notice that currently there is no link between Optimize for B2B and Optimize for Process ?. I can’t really drill down to the TN transaction from a process instance and vice vers in MWS. Is it how it is intended to be ?. To me it looks like a gap in the product. In order to get this functionality do i have to write custom code ?

Any thoughts on this would be appreciated.

Thanks,
