Are you trying to separate your own (for example) /home/dennis while leaving other /home subdirectories on the /home filesystem? You can do this by mounting /home/dennis under /home. Just make a mount point /home/dennis and add fstab entries. Nested mount points work, and are the way other filesystems are mounted on root. The only tricky part is that your /home/dennis should still contain lost+found owned by root (if ext4) and you will need to move all files and directories into the root of the /home/dennis filesystem.

I recommend using a mount point with root:root ownership and no access to others to prevent unintentional modification while /home/dennis is not mounted.
