Our company offers 2yr subscriptions, with the 2yr subscription fee paid for up-front. 

The challenge we have with setting this up in Zoho Subscriptions is that, after the first 2yr period, we would like to have the subscription auto-renew annually at the 1yr price.

So, as an example: initial subscription is $200 for 2 yrs and then, subsequent subscriptions billed at $150 annually.

Is there a hack or workaround to make this happen, by chance?
