Something we have been encountering with our composite items is dealing with scaling of quantity of one or more items within the composite assembly relative to the number of complete units being sold.

I.e. running the equation 2(n-1) on one of the assembly components where n is the number of complete units sold/being bundled.

Therefore when I am selling only 1 unit of this product, at point of assembly, the formula triggers and recognises that I need 0 of this item; or when I am selling 5 of this unit, at point of creating 5 assemblies the quantity is given as 8 etc. etc.

I know this would be quite finnicky in terms of execution, however it would remove the need for as much manual intervention and enable us to keep a much more accurate count of inventory - essentially just streamlining the inventory process a bit
