How do I set the context variables with a single call?

[TheOnlyTails]

Is there a way to set the entire context object with a single set call, like this?

c.set({
   username: "username",
   password: "password",
})

I guess you can set it up like this:

c.set('userInfo', {
   username: 'username',
   password: 'password',
})
