Hi,
The only way to make this work properly is via custom coding – possibly using the ‘asp_results’ hook to modify the results array order. Taxonomies are stored as separate object types, so I’m afraid we cannot integrate such feature.
If the taxonomies were created in the same order as the dates, then grouping may work. Use the ‘Use all from {taxonomy}’ option: https://i.imgur.com/MNylzo8.png
