Splitting products by textfield

[Shad86]

Hi guys,

 

we have a big problem.

We are a printing company and if you buy a product, it should be possible to choose if you want two motives.

Prestashop give us the possibility to activate the required textfields, that splits the products in the cart.

Thats great so far.

 

We need someone that can make this perfect.

The textfield should split the product completely.

For example:

 

Quantity discounts are:

50 pieces, 50$

100 pieces, 80$

 

A costumer adds the following:
50 pcs of product A with text field: "motive1"
50 pcs of product A with text field: "motive2"

 

He has to pay 100$ total.

 

I hope it´s understandable.

Or is there someone with another idea?
