Combining weighted attributes into a new attribute in FME Desktop

Hi all, I have a seemingly easy question. I have two feature classes that I have spatially joined using the spatial relator. There are two cities fields in this new feature. For the sake of the example, we can refer to them as Cities A and Cities B. Some values are null in both fields, however the Cities A is more accurate.

 

How do I combine Cities A and Cities B into a new field with priority given to Cities A, assuming it is not null. i.e. if Cities A is null and Cities B has a value, we use Cities B. If Cities A and B both have values for a feature, then only Cities A would be used.

One way to do this is to use Conditional values. This can be used in an AttributeCreator or AttributeManager. Create a new attribute called Cities and use a Conditional for the value. When Cities A has a value use Cities A, else when Cities B has a value use Cities B.
