Customisation of topic

Hi,
I asked question about customisation but you have not given me full answer and just label it “resolved”. Please, be more accurate. I provide you with information about previous inquiry.

Before
Good day Sir or Madam,
I have an issue I would like to discuss. I decide to use your booster in my site for shipping. The problem is I use shipping by weight (kg) for pictures and paintings by oil on canvas and the shipping rate directly depends on zip code (territory), specified in booster. However, there are also postcards (small goods), which shipping should be calculated by units not weight. The question is – can I customize the booster shipping calculator so it calculates the shipping rate by both weight and unit simultaneously. For example, one (1) picture 3 kg and 3 postcards. Either specify different rules for the calculation of pictures and postcards. Or any other way resolve this issue. I would be especially grateful if you write down the instruction.
best regards,
Vitalii

Your answer (it was not full) and PLEASE, consider clarification below!
Hi Vitalii,

That should be possible. You would have to use Booster’s Custom Shipping method with prices by weight enabled. Then you should also enable “Apply formulas” option and use a word quantity to specify quantity in your formulas.

Could you write it step>by>step since I can not find “prices by weight”. Where is it in settings? Again, there are two types of goods (for one shipping calculation should be by KG and another by item\unit). So how to make it possible for a customer to buy simultaneously both of these products and avoid a situation when 1 unit will be calculated as 1 kg and vice versa. Should I work with woocommerce settings? Thank you in advance!
