Feature Adoption > Group by 'Module'

In our Product Mapper we have grouped functions by Module, but when I go into the Feature adoption I can only group by feature and not by module. I think the feature granularity is not always going to work for us if we want a high-level view of module usage.

I can get the individual events in a dashboard by adding a ‘Feature performance’ widget filtered by Module, so can get the individual numbers, but essentially I just want a bar chart where I have all the events by some date granularity (week? day?) split by module.
