Combined Products? Is it possible or any plans to do it in future?

hi again.
for example, i sell cakes.
i need to track inventory and for example there are products like chocolate 100 kg in stock and sugar 500 kgs in stock.
i sell Chocolate Cake which needs 100 gram chocolate and 200 gram of sugar.
i need to combine the cake with chocolate and sugar stock.
so it means that if i have sold 1 chocolate cake then there should remain 99.9 kgs of chocolate and 499.8 kgs of sugar.

is it possible to create combined products?
