How to overcome missing query parameters in Databricks SQL?

Hi, there!

I'm trying to build up my first dashboard based on Dataabricks SQL. As far as I can see if you define a query parameter you can't skip it further. I'm looking for any option where I can make my parameter optional.

For instance, I have a table (start_date, end_date, country_code, unique_ids) and want by default to show the data for the last 7 days. But at the same time, I want to add two inputs where a user can specify his / her arbitrary date range.

When I don't provide any value I get a "Missing values for start_date, end_date parameters" error. So if I get a null in this case I can process it via SQL, but my query just fails.

Is there any chance to overcome this limitation?
