How to add costs to a produc category

Hoi together

We have products which belong to a product category.

Three month after we received the goods and the invoice we get more invoices for this product (for example Transport costs, Marketing costs, customs, ...). Ho could we Charge this costs to a whole product catagory (different expense accounts and cost Center).

For example.

100kg honey for 500CHF in product category food

three month later (honey might be sailed out completely until further invoices are comming in)

- 100 CHF for transport

- 100 CHF for marketing

With Kind regards
