Reporting and API access for voter Importance values

I want to be able to report on the 'Importance' values (Not important, Nice to have, Important, Essential) given by customers across all features. Specifically, I need a way to see importance per Company or per User in a list of features. Currently, this can be set in the UI but cannot be reported on via the web interface or accessed via the API. Having this data available via API is the minimum requirement for us to work with these customer values effectively.
