[Plugin: Minutes, Agendas, Newsletters]-Display newsletter per month

Hi all,

I wanted to display the newsletters i have per month. I added this shortcode

[minagnews-table show=newsletters year=2013]

[minagnews-table show=newsletters month=september month=october month=november month=december year=2012]

Here i have newsletters in the following months (sept-oct-nov-dec) and one in 2013 (January). I dont want the rest of the months to appear since they do not have any newsletters.

How i do this?

Thanks
