How to encrypt two folders: home and another?

Question

Encryption

Encrypted home folder with ecryptfs-migrate-home. It automatically mounts and unmounts on entry and exit, all is well. Connected another hard drive (with one ext4 partition) to /media/b. I want to create another encrypted folder so that the encrypted data is stored on /media/b and the decrypted data is mounted on /home/username/b automatically. How to do it?
