Brute Force Lockout duration

I have just installed the brute force ip lockout feature in Adv Sec. Very helpful to prevent DoS. One request: I see that it only allows a penalty box duration of 100 hours - while that may be ok for actual legit users who type their ip 10 times, it really should allow me to set these to super-long durations like 100 years or simple indefinite. That’s what really makes the most sense in this horrible climate we are now in.
My motto: Trust no one. For a thousand years. Rinse and repeat.
