Create Extended Query
You can add an extended query based on the stored queries you have already created. First, select 'Stored Queries' on the left-hand side panel. Then click on the three dots in the top right corner of your stored query and select 'Create Extended Query'.
This will give you several options to choose from depending on your needs.
If you choose to summarise the data, select the 'Summarise Data' button at the top right corner.
The following step is to select the fields that you want to summarise and the expressions that you want to use.
After saving the changes, give your new extended query a suitable name.
In order to edit the metadata, you need to click on 'Edit Metadata' as shown below.
In this case, you will be given the opportunity to add a summary, description and create a new category.
