[Plugin: Top Authors] show top authors of the week or month

I am running a multiple author news website in word press. I am using Top Authors plug-in to show the top authors. This plugin counts the number of post posted by the authors and arrange them in order where the most number of article poster is at the top following the least posters.

I want to know whether there is a way to control the range of time period, so I can show my visitors top authors of the week or top authors of the month… something like this…
