How quantity discounts apply different between groups of attributes in a single article.?

[Dimar]

Hello.

I have a problem to apply discounts.

Buy items sold per meter per roll and I need to apply different discounts, for example :

Apply 10% discount if arriving at 1000 meters from several colors .

Apply 5% discount if you get to 12 rolls from several colors .

 

Is there a trick or a module to do this?
What I need is to apply the discounts as follows, for example:

Red thread, 1mm per meter
Blue thread, 1mm per meter
Black thread, 1mm per meter
White thread, 1mm per meter
In this group 10% apply when reach X meter between all.


Red thread, 1mm per roll
Blue thread, 1mm per roll
Black thread, 1mm per roll
White thread, 1mm per roll
In this group 5% apply when reach X rolls between all.

Is there a trick or a module to do this?

Greetings!
