I think you should look at Aruba's API code to see how to do this very
elegantly.  essentially it uses the `cmd` as a key, can't recall what
happens if the commands are identical.
If it doesn't already handle your use case I would think it could be
easily adjusted to do so?

Would be interested in hearing your experiences.

HTH?
