Can Affiliates Plugin manage more than one level of referrals?

I’m wondering whether an affiliate signed up through the Affiliates Plugin can then sign up another affiliate under them and get a small referral fee from sales one level deeper than themselves. Or, can affiliates become a member of a group of sales affiliates that give them a bonus for sales within the group? Can the system track and pay out bonuses above what their percentages are, when certain sales levels are achieved? Thanks!
