Threshold?

Okay, you know the little change threshold button in a topic? That's directly related to rep right? I was wondering if there is a way to turn that to "all posts" by default in every topic for all users. Or if there's a way to shut that off but keep the rep system on. If there's not for either of those, I think there should be one. As I don't like the idea of not being able to see all posts unless I click that in every topic, and members not even knowing it's there.
