Extract values from dynamically changing indices from a list

Hi all,

I try to dynamically read values from a list, i.e. sometimes I need to extract the value at index 0, sometimes the value at index 5 and so on and then store the value to a new attribute. The index of the value I need to extract depends on the value of another attribute. The number of entries in the list is roughly limited to 10 in my use case, so I solved this problem with a conditional value in the AttributeManager. However, it'd be nice to know if there's a dynamic solution to this problem.
