Ability to choose specific outcome codes for the 'E-Learning Completion Updates Subject' System Setting

We've recently activated the 'E-Learning Completion Updates Subject' System Setting, which has been a blessing in driving our workflow performance and usage.

We're currently finding that the only option that will be automatically be applied is the C (20), however this is occurring for all classes. RPL assessments should have a RPL-G (51). Is it possible to set it (either through the class settings, or through a learning plan) so that the RPL-G (51) can be used for a cohort of students?
