when you have a plan (e.g. with "regular validity duration = this calendar year") it is possible to set a "renew in advance" time.
How can I configure a "pay in advance / upgrade in advance" time? Is that possible?
Something like " If you pay/upgrade in October/November/December 2012, you will get 2012 for free and a subscription for 2013.
Thanks for your help
