You cannot edit the usage details of a previously saved project. If your reuse details change, you will need to leave a comment to the publisher on your request outlining the changes, or in some cases you will need to resubmit your request.
You can change the name of your project by going to your Request Manager inbox and selecting the project from the sidebar. You will then need to click the edit button beside the project name.
Once you have input your new project name, click on the green save button to update.
