Call History download puts name & number in one column

When downloading the call history in a .csv format (spreadsheet), the caller name and phone number are lumped together in one field (column) with the name listed first.  I want to sort it by phone number but cannot do it because this column sorts by name.  When a caller is added to the address book, the phone number is in a field all by itself.  Why can't the .csv file be formatted this way?  It would also be nice if the first and last names were in separate filelds too, as follows:

Call Type   First Name  Last Name   Phone Number  Time           Date

------------    ---------------   ---------------   ---------------------   ------------   -------------
