A transformer, which combines AttributeValueMapper, AttributeRangeMapper and TestFilter

I'm using AttributeValueMapper, AttributeRangeMapper and TestFilter quite a lot, but I'm missing a transformer, which would have similar interface as AttributeValueMapper, but you could set a Test Condition to the source value like in TestFilter. If the value of the source attribute passes the test condition, the destination attribute would get the value from the corresponding Destination Value.

At the moment I usually have a TestFilter with AttributeCreators for each output port of the TestFilter. AttributeValueMapper is a good tool, but lacks the capabilities of TestFilter.

Of course I could use Conditional Values in e.g. AttributeManager, but they're always hidden inside the transformer.
