PowerBI App - Open or Collapse all tabs when App Opens

Hello everyone,

I am fairly new to PowerBI Service and has been exploring how to build PowerBI Apps.

I wanted to know if its possible to collapse or open all the tabs when the app is launched by the user.

Right now, it will only expand the first section or first report and the other section remains closed.

As you can see in the image above, "Opportunity Analysis Sample" opens up by default when I launch the app and you can see all the tabs that makes up this section. However "Retail Analysis Sample Report" did not open up.

Is there any way for all the sections to open up automatically?

Thank you
