relationships

1)A user can have many causes and a cause can belong to many users.

2)A user can have many campaigns and campaigns can belong to many users. Campaigns belong to one cause.

I want to be able to assign causes or campaigns to a given user, individually. So a user can be assigned a specific campaign. OR a user could be assigned a cause and all of the campaigns of that cause should then be associated with a user.

Is that possible? And could I set it up so that the relationships could be simplified like so:

User.causes = all causes that belong to a user

User.campaigns = all campaigns that belong to user whether through a cause association or campaign association
