make "transfer to temp file" per site

Hello,

Recently I found one of my SFTP servers does not support file renaming. It's a dropbear server with openssh sftp executable. From winscp's server capacities it supports posix-rename@openssh.com="1" and I can use mv from shell to rename files but I don't know why winscp has troubles to rename temp files.

Anyway, it would be helpful that you can make the global preference "Transfer/Endurance/Enable transfer resume/transfer to temporary filename" option to per-site, or a site can override the global option, most of my servers support file rename and I don't want to disable transfer resume just for this 1 server.

Thanks.

Thanks for your suggestion.
Will see if more people ask for this.
