@Phssthpok - You're using Windows right
Extract the files to FolderX, run a batch file or a script against FolderX contents that forces RO off (attrib command) and moves the files from FolderX to the Autoadd folder (move command) .
Maybe you could do the extract, attrib and move in one fell swoop with something like a powershell, ahk, or a ptfb script.
I'm not aware of any Windows unarchivers that provide an option to set/unset attributes - apart from the Archive attribute. Although I have a memory cell suggesting that Total Commander might have something - but that would be tantamount to using a jackhammer to crack a peanut.
