There would also need to be some "coaelscing" to define when the
(single) response was sent back. The first issue would be how the
multiple clients see the Report.

By special, I don't think you mean QP0/1 but a unique one per client.

That would be another way (which I think would currently work with the
existing APIs) of doing this putting the all the burden on the SA. (more
Reports needing to be sent) saving this additional complexity at the end
node.
If this is acceptable to all, then I will consider this closed.
