Extend field type GLPI Object to include Selection of KB articles

[derry43]

I want to create an approval process for KB articles and part of that would be a form to request approval.

I would like the field type "GLPI Object" to be extended to allow the selection of a KB article from either published or unpublished KB articles. Perhaps adding

Tools -> Knowledge base -> Published 
Tools -> Knowledge base ->  Unpublished 

Or perhaps even being able to filter the list of Knowledge base articles based on selecting a category and/or whether the articles are published or not.

Tools -> Knowledge base -> Published -> Category1
Tools -> Knowledge base -> Published -> Category2
Tools -> Knowledge base -> Published -> Category3
Tools -> Knowledge base ->  Unpublished -> Category1
Tools -> Knowledge base ->  Unpublished -> Category2
