Lets say i have an array stored inside a shared value.
It would be awesome if there would be a function which takes 2 arguments:

1. Existing Shared Value, we want to access (this value could be an object or an array)
2. A function, lets you select an element from that object (entireList) => entireList[index]

Output would be the selected element, but as a shared value.
