Is there any way to start a progression in the middle?

Let's say I was at a bet of 5 (just an example number) in d'alambert strat, with increments of 1 (go down 1 on win, go up 1 on loss). It seems if i set 'starting bet' to 5, it will start there but it won't go below that. I want it to start at 5 but go all the way down to 1 if neccessary. I set minimum bet to 1 in 'advanced bet settings' tab but it doesn't work.
