E.164 parsing for contact directory matching?

Hi,

Is there a way to make the up.useDirectoryNames function on a VVX phone match a contact when it contains the phone number in local format (e.g. 10-digits in North-America) and the incoming call's CallerID is in E.164 international format (e.g. +1-NXX-NXX-XXXX)? 

(...or vice-versa. It would be nice if contacts would match no matter the formatting used in the contact and/or CallerID. Right now, they have to match exactly. Leading 1, +, 00 or 011 should be ignored.)
