About 2-3 people call a lot, these are welcomed calls. But they fill up the call log immediately. Making it hard to sort out the other random callers that call perhaps 1x a week.
Can you put an option to 'accordian' style group together that same caller on the call log.
Like this
+ REPEAT CALLER XXX-XXX-XXXX
Click on the + opens all the calls from that same person. Pressing - will accordian style close that caller's call log.
This will clean up the call log nicely.
