Invoice List for some billing documets of a same costumer

Hi

I have a costumer that buy very different materials.

For some of those I want to create invoice list and for others no.

How can I do that? There is some filed in sales order that I can activate?

I can't do it in the costumer master data because if I do it all documents for this costumer will be able to invoice list and I don't want it.

Thanks in advance
