Please have option to set Backup To Folder path

It’s really nice the way you have the “Log files” folder (in settings) provide a default path, which includes the path all the way back to the ftp root. Can you please add this for the backup “To Folder” tab. Like maybe if I delete the current path and hit save, it would fill in a default path? Or have a button that would fill in a default path. The reason, is that when I clone a WP site to a new site, I have to figure out what the full path is. It might be a different host altogether with different root pathing. Thanks for a great plugin! Please reply if you have time, or if you want more clarification.
