Need number mask set not always from 0

[banqhsia]

Hi there, I'm making a site that uses ngMask.

I want number mask that is not just from zero. For example, /[a-zA-Z](1|2)/ have to use @2 as mask. But that becomes allowing like a0, B0... and so on.

Is there any implement can do to have number restriction not always from zero?
