Hi,
There is no option for that for now.
We're working on HikaSubscription at the moment:
www.hikashop.com/home/blog/380-hikasubscription-beta.html
This will allow for recurring payments, which do such automatic reorder feature. However, this is not available yet and will require the development of specific recurring payment plugins for each payment gateway which supports that capability, like PayPal recurring.
