Inheriting links between Data flow diagrams

[DaveH28]

Hi,

I am currently working on the software architecture for my current project. I am constrained to using Dataflow diagrams (customer request).

Could anybody help me with this, if i make a process composite, so that i can de-compose it further,  is there way to inherit the links from the level above, so that i do not have to put them in manually and label them the same.

E.G. Top level, 2 processes and an external with 4 dataflow links, 2 links go from the external to each process, so each process has 2 incoming data flow links.
When i decompose one of the processes i want the links to follow down onto the decomposition, so that the dataflow can be followed through and linked to futher processes.

Any help would be appreciated,

TIA
