Field extraction on post multikv field?

Is it possible to create a field extraction on a field that only exists after piping through multikv?

In other words, can I persist this:

index="os" sourcetype="netstat" | multikv | rex field=LocalAddress "(?<port>\d{5})$"

No, Splunk will not extract fields that are only present post multikv. This extraction will need to be based on the _raw field.

Well, to clarify, it will do almost just as you've set up above (though you're missing a field name for the extraction), it just can't be set up as an automatic extraction.
