Thread:Extension talk:Cite/page-argument in ref-tag

Are there any developments regarding the "References to different pages of same source" -problem as described in Extension:Cite/Cite.php except the "additional template"-solution? More specifically, any plans or efforts made to have page-argument in ref-tag? Or estimates how hard it would be to implement it so that following would be the outcome:

Page text like Argument A. Argument B. and references-tag like would produce ,  Details of source. into references-list.

Or additional note-argument which would simply add possibility to give some notes in every citation.
