How do I add auth to all actions of a Resource?

[amrecords]

I can use
userResource.create.auth(function(req, res, context) { }
to protect the auth action, but when I want to use the same auth check for all actions, I'd like to use something like
userResource.allActions.auth(function(req, res, context) { }

Instead I need to use
userResource.create.auth(function(req, res, context) { }
userResource.list.auth(function(req, res, context) { }
userResource.read.auth(function(req, res, context) { }
userResource.update.auth(function(req, res, context) { }
userResource.delete.auth(function(req, res, context) { }

Is a short version possible without producing lots of duplicate code?

Use userResource.all.auth(function (req, res, context) { }
