sorry if I was not clear
add preferenceID to Party, partyGroup, and change the userlogin to
preferenceID. this is a one to one. So each one can have preference
independent and specific to that level.
So the Party Group would be first, then add the Party that is Associated
then lookup the userlogin if there is one logged in, but this is not
reqired, just one way to structure veiws and code.
if you access a party then you can find the preferences by looking up
the Preferennce through preferenceID or do a view PartyPreference.
for migration you can have a view UserPreference for userlogin

you can further have preferences with partyreltionship and roles. By
Just Adding a preferenceID
