As mentioned this morning in the Database Managers Tessitura Community Group Meetup. I had thought I had a feature request in for this, but I guess I never added it to Ideas. Here's the idea:
https://community.tessituranetwork.com/ideas/i/ideas/option-to-send-analytics-dashboards-as-spreadsheets-excel-csv
"Analytics Dashboards converted to PDF for mailing will lose information if the data expands past one page. Individual Pivot widgets can be saved as Excel files, so it seems like it wouldn't be a stretch to have the option: it would just put every pivot widget into a separate sheet in an Excel file, and skip non-pivot widgets."
