I would like a unique list of contractors we have used on certain jobs. I don't want the list to be populated with several of the same contractors. In other words, we have used ABC company on 50 XYZ-owned jobs, but I only need ABC listed once. Is there a way to produce a lookup with unique names only? ie ABC on XYZ, JKL on XYZ, DEF on XYZ, ABC on 123, ABC on 678, etc.
