Scan for all existing Lutron Dimmers,Switchers

Hello, I'm new into Lutron lighting... Is there a way/tool to scan for all existing Lutron Dimmers,Switchers already connected?
A client reached me to add new dimmers to Lutron system but I dont have the Project file, and I cannot extract since Codever is 5.5.4; I do have the XML file to integrate with 3rd party RTI, but I would like to see the Serial numbers.... I just trying to make it easier if have to do whole project from scratch. HELP Please.
Thanks

Hello maastechs,
Thank you for your post.
The only way to add to the system is to have a copy of the project file. If you don't have a copy of the file the it would need to be written again.
