[Request] Big Countdown Timer UI to start from 20 seconds.

As it stands the current countdown timer UI only starts at 5 seconds when there are a few jobs that have prepull openers above that.

I play as a Dancer mainly and my prepull timing is around 15 seconds and as I understand it Samurais timing is 14 seconds now. Giving the option for the countdown timer UI to start appearing at 20 seconds would help with this.

More options can be implemented if some players prefer those like 20, 15, 10 and 5 seconds.
