Hi Chloe,
There isn't a direct way to report on this through Genesys Cloud. I believe you could write the outcome to custom participant data and then export it via Performance > Interactions or use a data action action to write it to an external database or CRM tool.
There is an idea on the Genesys Cloud Product Ideas lab: Report Custom Attributes updates via scripts that may be worth adding your use case and voting on so that you get updates as the idea progresses.
