handlebars.js - Can Meteor Templates access Session variables directly?

Question

In my Meteor app I find myself writing a lot of things like:

Templates.myTemplate1.isCurrentUser = function() {
  return Session.get("isCurrentUser");
};


Templates.myTemplate2.isCurrentUser = function() {
  return Session.get("isCurrentUser");
};

I need many different templates (I'm using handlebars) to access the same simple value stored inside Session.

Is there a way to avoid writing the same function over and over again? Thanks

Building on @cioddi's answer, as you can pass parameters to the Handlebars helpers, you could make it a generic function so that you can easily retrieve any value dynamically, e.g.

Template.registerHelper('session',function(input){
    return Session.get(input);
});

You can then call it in your template like this

{{session "isCurrentUser"}}

Note that the auth packages come with a global helper named CurrentUser that you can use to detect if the user is logged in:

{{#if currentUser}}
    ...
{{/if}}
