Could the short title field be used to disambiguate a citation ?

Hy,

I am wondering if the short title field (or any other field) could be used to disambiguate a citation since there is no option in the footnote template to do this.

This field should also be automatically added in the bibliography as a way to indicate how the reference is citated in the document. 

I found that in the citations output style section there is an option to differrentiate ambiguous ciations, but I coudl not find it elswhere. I that a bug or just an oversight?
