Chain integration with Cordys?


In several projects I have been using Cordys BOP4 platform. I really like the multi-tenancy possibilities within the project. Also the Provisioning Component of the produkt is highly appreciated and used.
However there is one thing that i sometimes run into.

Chain integration

Within the projects we have several Organisations that participate in the process of chain integration. They work with each other and they handover tasks to each other.

However currently the modelling of such "inter Organisation processes" is not possible. You can sent tasks to other Organizations but you can not model this with BPMN models.
This is a pitty because you loose the control and monitoring of the total process. Maybe you can customize this and implement it, but it is not present (yet??) in the Cordys project.
