The question is not clear.
If you mean that when you click in "Back to me" option/link at the bottom and it should direct to someone else then its not possible (for you), since you have already specified when you first established your self in the Family Tree and only built the tree around yourself.
BUT it should be different for the person you are sharing it with, if he/she is already part of the tree and you share it through Family Echo site only by putting in the email of the other person. It should direct to that person then.
