Improved Mask Attack
If I already knew the first 2 letters of a password or at the very least the range of what the first 2 letters are, is it possible to limit mask attack to these only?

Like I know that the first 2 letters are numbers from 1-25, can I limit hashcat to these only?
use rule with the wanted numbers with -a 0
Look at the custom character set parameters (-1 / -2 / -3 / -4)
