[mrtg] extracting one value from two in CISCO-RTTMON

I am trying to extract an average jitter stats from a Cisco device using
CISCO-RTTMON-MIB and I am getting the following:

# snmpwalk cisco .
enterprises. = 60
enterprises. = 56

The stats in this table,  rttMonJitterStatsEntry  (OID are stored for 2 hours, I believe, which may
explain the two entries.

As you can see from the output, the groups are timestamped and are
rolling, so the OID's changing.

Is there a way to get the single, latest reading into MRTG, without too
much complication. I don't write scripts for a living.

Any help appreciated.
