well this is just plain math, thats all possible masks for your given password-style (8 chars + 2 digits, digit position unknown)
9+8+7+6+5+4+3+2+1 = 45 masks
there is no* other way than this
* it would be possible to use rules instead of plain masks, but this way you have to generate tons of rules for every combination of digits 00-99 for all posistions, and never the less, the keyspace would change
