Does anyone know the answer to this?

A keycloak admin may want to enforce a specific password policy for one APP but a different (and conflicting) password policy for another APP.  

E.g. first policy requires one special character whereas second policy prohibits any special character.  Is this supportable in Keycloak?  I am thinking that two realms could be defined to do this but wouldn't that defeat single-sign-on across the realms?  Any thoughts?
