I have a somewhat similar request. (I believe it would solve Chaim Holtzer's issue too).
Can we have groups to which phone numbers and emails could be assigned (0-9 &/or A-Z). We could then select the target group of emails and phone numbers for the job at hand by using the group. For example a work email could be placed in group E for emergency and W for weekly bulletin but not M for marketing.
The "Desc" isn't enough to filter. Example: some want to be contacted by cell and some don't. Some want emails at work, some don't.
