Not sure this is in the right forum, but I'll soon find out.
I am a developer and have been looking at a way to link products together so that if a customer makes a purchase of a particular product then another product that is not visible to the customer also has its quantity deducted by a built-in factor.
As an example, if we sell an item that comes with 2 bolts, then the quantity for the 2 bolts is also deducted (from the Bolts product which isn't visible to the user)
The issue I have is not the initial purchase as that change is working, but when an Admin makes a manual change to the quantity for that order. I cannot find a way to make a similar change to the linked product.
Any help in pointing me to where this might be would be appreciated.

Thanks
