You can use export functionality even now, just navigate to Workspace tab, choose your custom filters and export the data for further reporting and analysis. Moreover, if you click on the Details link under each object's categorization summary on the top of the screen, you'll find another way how it export the data from BV.
Just on a side note, Veeam Reporter can already create reports based on BV categorization. Have you considered using it?
Hope this helps.
