Click to copy property and variable references for use in other formulas

Please add a way to click a property or variable name to copy its reference, then paste it into another item’s formula. zZ should automatically resolve the correct path to the source property or variable based on where the reference is pasted.

For example, in the attached screenshot, I would click Formula (Qty) in the Lumber item to copy its reference, then paste it into a new item’s formula. This would insert something like [../Qty] —using whatever syntax correctly references the original item’s property/variable.
