script for auto-generating requirements objects from operations, signals and events

Hello,

Has anyone produced a script that takes the descriptions from operation, signal and event objects generated in a sequence or activity diagram and represent them as requirements objects, partitioned according to the partitioning in the diagram? We would like to produce these diagrams as realisations of system level use case flows, representing the various sub-systems and the operations, signals and events that belong to them. These can then be used (if carefully worded) to produce a first cut set of requirements at the sub-system level for each identified sub-system.

Many thanks,
