Is there an aging mechanism whereby the application can automatically ignore posts that are n-days old, or with less than n-number of "like" hits? Reason I ask

Is there an aging mechanism whereby the application can automatically ignore posts that are n-days old, or with less than n-number of "like" hits? Reason I ask is that I've just started using greeder. I tend to also get ovsessive-compulsive about making sure everything's read and ticked, so i can definitely see this as becomming a problem.
