I am trying to convey the idea that something is done in a customised way but all I found was customarily (link to Merriam-Webster definition) which stems from customary so it's not what I need. Is there such a word?
It should fit in a sentence like this one:
The items that I ____ manufactured are safely stored.
I know customised implies the creation of the object but I only do the manufacturing part, while the customisation is done by somebody else. I know the sentence can be reordered but I would like to know if there is an adverb I can use.
