[Plugin: GD Star Rating] Show Amount of Votes from last week

I’m looking for a way to show only the votes (up-thumbs in this case) from the last week. At the moment, the plugin has the following option:

“Use only articles voted for in last # days.”

Here I can specifiy the posts that should be shown, but it doesn’t show the amount of votes from that specific week.

What I want is this: Postname A has a total of 30 votes, of which 3 were submitted in the last week. So “Postname A –> 3”.

Any ideas how and if this can be done?
