How to limit a voucher to products that are not already discounted via per-product special rules?

[stratboy]

Hi, I see it's a common issue but maybe there is some newer way to solve I don't know, but I really hope though...

It's quite obvious that the merchant should be able to create a voucher and have the option to not apply it to products themselves already discounted. That seems not the case with prestashop.

For now, the only way I can think of, is to put the discounted products on a special frontend-menu-hidden fake category, and then assign the voucher to all the categories but the fake one. Basically, working out the logic upside down... Quite crazy, indeed.

So, is there a smarter way?

Thank you
