[Plugin: FreshPost] Count number of posts created with a specific custom write panel

Hi… I’m using the latest version of Flutter with WP 2.6.1 and I have I sort of weird question.

Is there any way to determine how many posts have been added using a specific custom write panel?

What I want to do is to be able to assign a maximum number of posts per write panel, and once that number is reached, remove the write panel from the admin section.

Thanks!
