How to make a recursive mkdir with Rails SFTP?

Is it possible to create multiple level directories like /2017/04/11/ on a FTP Server via sftp.mkdir! "/2017/04/11"?

It returns Net::SFTP::StatusException: Net::SFTP::StatusException because I have neither a /2017 directory nor a /04 subdirectory.

Just sftp.mkdir! "/2017" creates one level.
