Add more Presentation Scenes to my Scenes library

Hello…!!!
I started working with Solidworks recently.
Could you please tell me how to add more Presentation Scenes to my Scenes library?
How and where I can download more “background.p2s“files?
I am sick of applying “courtyard background” for every car I model.
Thank you.
PS: I saw very nice backgrounds on renders. Can someone upload one or two if you can? Mostly once for vehicle displays.
