Selective Non-Overwrite

Hi, I am going to upload the update folder for Coppermine photo gallery to my website. There are about 93 files and folders in this update. My question is: I have 2 or 3 files that need NOT to be over written during the update process. Is there a way to set smftp to not over write only certain files in a case such as this? Except for these few all the other files need to be over written.

Thanks for your attention. It is appreciated.
