Customize products and quantity

Hello there,
I would like to but this extension but I really have an issue.

Maybe you will be able to answer.

My project allows to customers to create a personnalised portrait of their family.
They can add as many as people they want. And they have to customize every single family member with the attributes (height, color of hair, skin, etc). Once it’s done, they can add all the members.

Does this extension will allow me to do so?

In the free version I love exactly how it works. Could you please tell me if it will be possible with the premium version?

BR,

Johann
