Is there any flag to differentiate between sites on the same customer.

Hi,

Please may you help us on the below issue.

We have a new customer and he has seven sites.

First 5 sites is a site that he will receive the goods on it and the invoices you can say these are

normal sites BUT the two remains sites will be franchise sites.

So is there any flag or an option to differentiate between sites on the same customer?

In other words is there any way to mark a specific site and to unmark the other sites.

Thanks

George
