What I've done to modify jhipster entity like a Relationship to add new tables was:

1. (save project before anything happens :p) yo jhipster:entity TableToEdit and Edit whatever you want.Who to editTableOrAdd
2. Then add the new tables.(optional)
3. I had then I just had to do change or remove all the tables of the DataBase, to generate the new fields and relations on the SQL part automatically.

Note: If after this steps, it has any error, serverError or something I regenerate de entityregenerate Entity. Of course if you want to keep all your data this is not a good alternative.
