Automatically fill defined fields at startup

Hello,

Is there a way in Looker Studio to predefine fields with specific values?
My goal is to incorporate a simple authorization structure into a Looker Studio evaluation. At startup, a field should be filled with the user’s email address, which then acts as a selection criterion for another field.

Greetings

Yes! You can define default values for filter controls and for parameters, both of which should work for something similar to your use case.
