Static sender SMS contact number?

[Wmljan]

Is there any way to cause a fixed sender contact number when receiving SMS notifications from eyez-on? Every text is the next sequential number and I would like to assign “Alarm” as the contact name, but really don’t want to enter a thousand numbers under that name…
(I can do it using MMS, but want one style (MMS) for standard arm disarm notifications & (SMS) for alarm notifications with different alert tone)

No unfortunately, we have no control of what number your carrier assigns to our messages. Some carriers assign it 999-999-9999 while others seem to assign sequential numbers.
