Introductory Question - PPP and Modem Init Strings

I am familiar with the User Modem init strings in the Modem configuration
area. These are 'global' to communications environment.

1) Can I set modem init strings for an individual Phonebook Entry?? I have
examined the DUN user interface and the RASPhone.pbk. I am familiar with
Modem - GUID registry key.

I would like to be able to send AT Commands to a modem and STILL use PPP
from DUN, probably a private DUN Phonebook.

Thanks,
-- John
