adding new phone number or e-mail to existing contact

I feel really stupid asking this, but I can't find the answer anywhere, and this seems like something a BB should be able to do--especially since my last phone ("free" flip phone) could do it.

When someone who I already have in my address book calls me, I want to add their phone number to the existing entry. Or, if they e-mail me, and I don't have the e-mail address, I want to add their e-mail to the address book entry.

I can't figure out how to do this other than by copying and pasting. Why can't I update an existing entry with a new phone number or e-mail? Basically, I want to hit the menu button and have the option of adding the phone number or e-mail to an existing address book entry. Why doesn't this option exist?

Or does it, and I'm just being obtuse?

Believe it or not... Copy paste is the only way to do this!

Wow...just wow.

How long has RIM been doing this, and they're outclassed by a Samsung SCH-a870 in this feature?

Is there a way to request new features with RIM? Maybe this could be in a subsequent release.

My sentiments exactly when I found this out. I have already made this request to RIM.

Lets say I've a contact John in my adds book # 323 333 3333

that's it.

Now John calls me from his work/desk phone 444 222 1111

I'm done with my call and i see 444 222 1111 in my call log.

I should be able to

Simply click on the name and have the option of either
a. add as new contact
b. append or modify existing contact.

If i select option a. I enter a new name and I'm done

If I select option b. I should

i. be able to replace an existing number (with confirmation)
ii or insert the number into an empty phone field with no confirmation.

I find it unacceptable that a $500 phone cannot do this. All my old Nokias and Sonys have been able to do this for years.

PS: Please don't tell me to copy and paste. That's a LAME work around and not a real solution.
