How can I collect repeated contact entries under one call log entry? I'm running Cyanogen 5.0.8 and previously had stock 1.2 before this. On both releases I'd like is to be able to able to collect repeated call log entries in only one single entry reflecting last activity, whether it is "received", "missed", or "dialed". When the entry is to be tapped all activities related to the contact would be shown.

Is any one familiar with such feature and how can I achieve it on my phone?
CyanogenMod 6 does this feature because it is native to Android 2.2.  See this CyanogenMod issue report for more details.
