Adding two unrelated fields into one value list

[Ertjie]

Hi there. I was wondering if it is possible to add two unrelated fields into one value list? I want to combine my supplier emails (Supplier table) and my customer emails (Customer table) into one value list, example value list called email address... Any ideas or comments?

Why don't you roll them all into one table of Contacts and mark each contact as Supplier or Customer (or both)?
