OKS: Contract Renewal, contract is for 12 months but it starts on the 15th, is it possible to have t

Example:

Original Contract is 15-jan-2015 to 14 jan-16 for $120

billing schedule

15-jan-15 to 31-jan-15 amount =$5

01-feb-15 to 28-feb-15 amount =$10

and so on

For the renewed contract I would want

15-jan-16 to 31-jan-16 amount =$5

01-feb-16 to 28-feb-16 amount =$10

and so on

Is this possible without a customization?

Thanks in advance
