'Add Item to Array Variable' function in Tools section

[#1]

It would be really useful to have a function to add an item to an array variable. This should allow you to enter the name of an array variable (or even better, select it from a list) and provide the item input (string or object) and Fusion would add it to the list. There should be no need to provide the existing array contents as an input to the function like there is now with 'Set Variable'.

This new function would save the repetition (especially within an iterator) of getting the variable then setting the variable again over and over. This would reduce Fusion operations and UI/config clutter.
