WooCommerce Pre-Orders

Currently, this extension only allows for adding a fee when setting up for pre-order. In my case, I would actually need to give a discount when there is a pre-order.

I would also need two different timers: one during which the pre-order is available, and another marking the days until the product’s release. These two periods are actually quite apart for my product. This would allow my product to be displayed in my shop after the pre-order phase, and before its availability.
