Can Feruchemical Nicrosil Store All Types of Innate Investiture?

[Trusk'our]

We know that it is possible to store Bio-Chromatic Breaths inside a Nicrosilmind, which is essentially just a small piece of Innate Investiture. Does this mean that if someone from Scadrial, Roshar, or some other Shardworld where people have innate Investiture but who don't have any Invested powers, could they store their Innate Investiture as a Nalthian could store their Breath? Or is there a difference between a Breath gained from someone else and your own, personal Breath?

there is a difference between breath and regular innate investiture.  someone from Scadrial, for instance, does not have a breath, unless one is given to them.  and breath is designed to be able to be given away - it is designed to be able to be torn off. so storing a breath is a bit easier than storing say a normal piece of your innate investiture.

I cant find where this is confirmed anywhere, and it's not how feruchemical nicrosil works in all the instances we know of so far.  Feruchemical Nicrosil can stores the ability to use a given Investiture and (at least in medallions, unconfirmed with a ferrings) it does so as a discrete thing that gets put back like a coppermind.  It can store the ability to use a given allomantic or feruchemical ability, as well as the ability to use a surge or a Divine Breath.  

There is a WOB that confirms Nicrosil can Steal Biochromatic Breaths with Hemalurgy, if that's what you are thinking of.
