Achievement Badges based on points

Hi

I am wondering if it is possible to set up badges that are purely based on points earned through activity on my site.

I notice that there is already an Achievement called "Points Achiever" and I can see that I can vary the frequency at which this achievement is earned. What I am wondering is if it is possible to have multiple "Points Achiever" achievements, each one set at different frequencies. The idea being that someone can move from "bronze" to "silver" to "gold" to "platinum" all based on the frequency of a users activity.

Many thanks

Steve
