Enable us to change sender's display name on incoming email - their name, not ours
I receive emails from 'info', or 'customer service', or 'Bob', or other unidentifiable/common names, and want to be able to personalise regular/important contacts so their email display name is meaningful to me. I thought saving them as a Contact would mean the Name would be displayed, but they didn't work. Also tried editing the e-contact card...no luck. The Nickname seems an obvious choice to me - I imagine lots of people would want to identify incoming mail by the nickname they've given their contact, but that didn't work either.
I know the official procedure is to ask them to change the settings on their email programme, but not all our contacts are personal friends, and most won't want to change their display name for everyone just to make one person happy. Please enable us to to personalise our inbox (using Contacts) to identify between the various 'info's', 'Bob's' or whatever.
