Warning for outdated temp file overwriting remote file

Normally I double click the file in WinSCP and edit it in Notepad++, when I save the file in Notepad++, it will automatically upload to remote server.

Somehow my colleague added new snippet in the remote file after I opened it in Notepad++, the file in my Notepad++ does not have the new snippet, i click save then WinSCP will upload my file and my colleague new snippet gone.

Can WinSCP warning me when I try to update the remote file if the modification time of the remote file is different from(newer than) the moment I opened it in Notepad++?

Thanks!!
