Suggestion: optimized used of "use field instead of record number"

This functionnality seems very attractive, but it seems to me that the way it is currently working is not of too much help: we have to specify extra information (the preferred field) with the classical {author, year}. Then, the label of this option is confusing, because when using record number, we just have to specify the record number and nothing else.

I then guessed, that it would be OK to give solely the new field, let’s say <label>; like this way : {#<label>}. This would be of great interest (at least for me): it will allow to manage your own references and to call them in your documents with no other information to give. 

Is this to be implemented?
