ListView ordered from the bottom list

Is it possible to sort from the bottom list when using a list in a list?

I have an App State that points to a Data Type. Within that Data Type is a list. Within that Data Type is also another list.

So I create a list view by using the generate children from variable.
I then point to the App State and select the list.

Then I create another list view using the generate children from variable and select the other list view and then select the list within that.

This means I see the original list with each of their sub lists.

But what I would like to do is sort by the index of these sub lists.

So instead of

Main List 1
-Sub List 1
-Sub List 2

Main List 2
-Sub List 1
-Sub List 2

I would like it to appear

Main List 1
-Sub List 1

Main List 2
-Sub List 1

Main List 1
-Sub List 2

Main List 2
-Sub List 2

Does anyone know how this can be achieved? (Included is an image of the components screen)
