Using wildcards

-- url of the page with the problem -- : www.1stopmotoronderdelen.nl

-- Joomla version -- : 3.6.4

I want to setup a discount/coupon for a large number of products.
For me it would be fairly easy if it was possible to use a wildcard to select the products in the discount/coupon product field, but it looks as if thast is not possible.

Is there a way to do this within hikashop itself ?

I already have a workaround in my mind, by creating a specific category, and running a database query to add the intended products (by wildcard) to that category, but I would prefer the possibility of doing through hikashop backend itself.

I would like to give a discount/coupon only on products that have a product_code starting with 'abc'.
So in the product restrictions I would like to insert 'abc*' so all products starting with 'abc' would be valid for that discount/coupon.
