As a user, I want to be able to group/filter the past analyses by prediction outcome so that I can focus on patients with the same disease classification

Additional context
When asked, testers expressed a desire to only see the COVID-Net predictive analysis values after conducting their own reading of the radiological images. So in a clinical setting, this would be impractical. In a research setting, we are unsure how this would affect the workflow.
