Setting up Accounts Payable payments terms, multi-level/cascading discounts

I'm struggling with how to properly setup an Accounts Payable payment term for the following:

Terms: 5% discount if paid within 0-10 days of invoice date, a 3% discount if paid in 11-15 days of invoice date otherwise no discount

Can anyone provide help on how this can be done?
