ACKCODE on recovery alert

Hey -

Question on ACKCODE - it appears this purposefully changes to 0 on recovery
message.  I was curious if there is a way to include the original alerts
code on recovery messages?

My use case it that I'm using a script to open a pagerduty.com incident
using their API directly and using the xymon ACKCODE as the incident_key.
 If I have the same ACKCODE given with the recovery message I can resolve
pagerduty.com incident when I get recovery from xymon.

Thanks,
Andrew
