Can you backup multiple theme configurations in ADW?

[easyjet]

Hello,
I have played around with ADW for a week or so and love it, setting up my icon shortcuts etc for a downloaded theme. My question though is that the "backup desktop configuration" command appears to just backup up the current version only. Is it possible to backup and store more than one theme configuration at a time with different icons, etc? If so I need instructions, as I haven't been able to figure that out. Or is that only in the ADW-EX? Also, if I purchase the ADW-EX, will I lose the current ADW configuration/setup?

After taking up so much time to set this theme up, I would like to move on and try others...but don't want to lose all this time and work. Thanks so much!!

GO THUNDER!!

Anyone?
I envision setting up multiple themes with the icon shortcuts on the multiple screens, saving each configuration and then changing them out frequently. Is this possible?
