select signal from each bus in array of busses

Question

In the first part of my Simulink model I created a bus array as described in the official documentation from n separate, but equally defined busses.

For the second part I need to get one of the bus signals from each bus in the array. I managed to do so with a MATLAB Function block by iterating through the array elements and copying the data to new arrays. Unfortunately I have to implement it without MATLAB Function blocks.

Is there a way to extract a single signal from all n busses in the bus array without using n selector blocks like in the documentation (image below: Selector4 and Selector5)?

Consider n arbitrarily large so that an implementation with selector blocks is unacceptable.

I found a solution myself. It is possible to put a bus selector inside a For Each subsystem:

This will result in n-dimensional output arrays.
