Palm Treo 680 Contacts feature?

[hal100]

Hi all!

OK, so I got this inquiry: I'm receiving a lot of SMS from a single corporation, that uses a lot of numbers. I wish to be able to tell that all these numbers come from the same source. So far, I've been adding the newer phone numbers to a series of entries for the same contact, i.e. Corporation X, Corporation X - 1, Corporation X - 2, etc. The Palm OS Contacts allows me as much as 7 phone numbers per entry, so the amount of entries is getting really big. All these phone numbers come from the same country and share the same prefix, i.e. +AA-BBB-XXX-YYYY, where XXX is the number's prefix.

Is there a sort of code that allows me to identify all these numbers without the hassle of entering them into a Contacts entry, perhaps something similar to {weird code}+AA-BBB-XXX, in order that the Palm Phone can tell it comes from such country, area code and prefix? The Palm Phone app has a Dial Preferences panel where I can add a dialing prefix to a 8 to 4 digit number, but that's not what I'm looking for (besides, there's more than one corporation whose numbers I wish to ID in mass ). Any suggestions, ideas, any weird code you know about?

TIA!

Not one? There ain't something like *#PBX# ?
