Setting fields as primary/secondary?
I have a contacts table and an address table. Some cntacts have 3 or more addresses. I am going to display each address within the Contact layout via a portal. When Invoices are genrated (invoices table), I want the primary and secondary address to show up on the invoice. Anyone care to share techniques on how they mark addresses as primary and secondary for displaying on, let's say an invoice, without having to manually select each address to add to the invoice each time?
P.S. I'm using addresses as an example, but I have other fields to apply this to, so I just need to learn the general technique to apply it across my solution.
