Prestashop 1.6.1.6 product ranking in category

[partssupply]

Hello,

 

I`m creating spare parts site and I need to rank product in category by reference number to be the same number as in drawing (category image).

 

I think best way is to create each category as tool (with drawing in category photo) and to get products assigned to that category, but I need products to have they number and I need products to be ranked by that number. 

 

And same product can be No. 1 in one category and No. 3 in other category. So I need to state product number or position in each category manually. Example site:

And I attached photo with basic view how it must to look...
