How to hide child product and remain it accessible through parent product?

[borro]

Hello.

I've assigned extra charge for child products in parent product at the last tab. But I haven't assigned whole price for child products in their cards.
So when I open child product direct from the catalog there is no price and Buy button(by the way is it a bug?).
Is it possible to hide direct access to child products and make them accessible through parent products card only?
If I make child products unpublished they dissappear and from parent drop down list at all.
