Can we assign ScrollViewReader's scrollTo target before a view opens?

I have a scrollview that has values 1 to 30. when first opening the view, I would like the default scrollTo target to be assigned to 15.

At this moment I cannot get it to work. I can get the target to update once the view is open and I click on one of the buttons.
