Sort Performance Call Log Report by Users Extension

We need to be able sort the call log report by the users extension. RIght now we can sort by "from", "length", "start time" and "direction". When creating a departmental call log report with multiple users being able to sorrt by the extension makes more sense so each user can see their calls at a glance. (yes I know they can sort it themselves in excel, but that is assuming they are proficient in excel). it makes more sense to juast have it sorted when they receive it.
