[Looker Studio] Auto-select in a dropdown in a report

[invisible]

Background

I have a Looker Studio report with a dropdown that has integer values sorted in descending order (largest value at top). These integer values are dynamic / constantly changing but they always stay in the descending order. There are multiple charts and a table in this report page that are cross-filtered with the values in this dropdown box.

Question

I would like to have only the largest value in the dropdown box (top value in this case) auto-selected when someone opens the report. This will ensure that the data associated with the largest value in the dropdown box is cross-filtered across all charts in the report. How do I do this? Can someone please help?

It is also worth mentioning that I am not using Looker Pro and cannot use LookML afaik. 😞

Thank you!
