How to group by DATE_TRUNC in Dremio with original column name as alias [in Superset]

Question

I'm using Superset for BI, with a Dremio backend.

This works great, except when attempting to change the "Time Grain" of a date range selection.

In Superset, if I choose a different time grain, like "day", it correctly creates a GROUP BY modification to the native query that looks like this -

SELECT DATE_TRUNC('day', dob) AS dob,
       group_name AS group_name,
       location_name AS location_name,
       sum(amount) AS net
FROM  my_table
WHERE dob >= TO_DATE('2021-09-03', 'YYYY-MM-DD')
  AND dob < TO_DATE('2021-09-10', 'YYYY-MM-DD')
GROUP BY DATE_TRUNC('day', dob),
         group_name,
         location_name
ORDER BY net DESC
LIMIT 10000

But that fails with Expression 'my_table.dob' is not being grouped

If I execute a query directly in Dremio and give the column a different alias, it works -

SELECT DATE_TRUNC('day', dob) AS d,
       group_name AS group_name,
       location_name AS location_name,
       sum(amount) AS net
FROM  my_table
WHERE dob >= TO_DATE('2021-09-03', 'YYYY-MM-DD')
  AND dob < TO_DATE('2021-09-10', 'YYYY-MM-DD')
GROUP BY DATE_TRUNC('day', dob),
         group_name,
         location_name
ORDER BY net DESC
LIMIT 10000

Superset uses an alias which is the same as the original column name, so dynamically changing the datetime granularity is broken. I don't know of a way to force a different alias for the time column.

Does anyone know a workaround?
