Change link in Project manager

I’m using the plug-in Projectmanager on my site.
At the same page i want to use the wp comment-function, to post a unik comment for every dataset in ProjectManager.

My solution for this is to create a post/dataset. Then I can use the comment-function for the datasets.

But there is a problem. When I list the datasets from ProjectManager there is a link to the dataset. I wan’t to change this link using the permalink to the post.

Is there anyway to do this?
Or is there some other way to solve this.
