Oxogen/fuel trim sensor bank 2 sensor 2

I see the primary and secondary in front of and after the Cat. The issue I am having is getting fuel trim readings on each bank of the v-6 engine. I know it would be vaid on a four cylander but with two banks on a v-6 I need to know how the fuel trim is doing on each bank. It might be that they did not provide two seperate fuel trim readings for each bank but that would be problematic in diagnosing engine issues since finding an issue becomes too difficult for a scanner
