Hi, just a thought, it could be smart to connect eCommerce "Publication periods" to discounts (Order discounts/Sales discounts) and maybe allow adding multiple periods at once. This should replace the current date pickers.
For example, if I want to repeat a discount each year in the period 1 January to 31 Jan. and from June 1st to June 30th. I just make two periods and adding them to the discount.
