Relationships going "through" an element

[telune]

When modeling a rather big and complex Software System, I often found that I model in my head a relationship between element A and element B as "going through" element C. This comes natural when I have to model services like API gateways or reverse proxies: e.g. I want to model the fact that a GUI (deployed in a browser) is in relationship with a back-end service (deployed on server X), but in some cases it is also important to communicate that the relationship "passes through" a reverse proxy that may be deployed on server Y.

I know that I can model this creating a relationship A -> C and another C -> B, but this quickly becomes cumbersome as C is typically used as gateway for a lot of different communications, and the original relationship A -> B (which is the actual "semantic" relationship) gets lost.

Are there plans to support this kind of "going through" relationship feature?
