Firefighter needing help with notification customization

[AC Question]

I'm a volunteer firefighter. I receive call outs over SMS, but they don't come from the same number every time. However, they do all begin with 770. I'm trying to find an app that will allow me to define custom notifications for SMS messages based on a regex against the sending number or some type of wildcard or even just area code matching. Has anyone heard of such a thing? I want to set a notification specific to my call outs that I know will wake me up in the middle of the night.

Do you get a lot of texts from other numbers at night?
