Users post their status only on their post

Hi, this is what I would like to achieve with this plugin, is it possible?

Users submit their post, but its a different post type: projects.
On the front end of their post, I have a tab that is called blog, so they can submit updates to that PROJECT.
So what I need is for them to update their status, but they can only update status on the projects created by him.

Does this plugin allows me to do so?
