Denon 2312 saving settings to laptop.

Hi, I own an 2312 which i am really pleased with & had no problems. . I ran audyssey a few months ago & saved the settings to my lap top. Today i have made quite a few settings (due to being snowed in in the uk) & need to save the changes. If i run save again, will i have the original file as well as the new one & if so can i keep both & rename them
Thanks for any help, Mark.
