Additional Information:
The submittal's status must be 'Open'.
Renaming a PDF attachment will automatically update its name in each step of the submittal's workflow where the attachment was included.
Only PDF attachments uploaded to a submittal can be renamed in the project's Submittals tool. If a PDF attachment was uploaded to another Procore tool and then added to the submittal, the PDF attachment can only be renamed by users with the appropriate permissions on the other tool.
