User status to prohibit automatic creation of PR

Hi Gurus,

I have scenario when project needs to be released in the beginning of the project for incoming order analysis of the project. Now if I release the entire project, the PR is generated automatically, on release. I want to restrict this.

For this I have created a user status. and I am trying to prohibit the creation of PR from project. But its not working.

Can anyone please help on this

Thanks
