Second Sort-Criteria For The Product List

[si.lithium]

Hey Folks,

 

in the Backend there's the option, to define only one default sort-criteria for products, e.g. "Price".

 

Is there a way, to define a second parameter, e.g. ...SORT BY 'PRICE', 'Reference'...so if two products have the same price, they will be sorted by the second criteria.

 

I've already tried to change the SQL-Statement in the Controllers, but the frontend is ignoring the second criteria.

 

If there is any possibility, to give a second criteria, I would be very happy!

 

Thanks in advance.

 

Best regdards,

Matthias
