ember cli multiple defs inside single file and breaking naming conventions

Is there any (tricky, dorky, or otherwise frowned upon) way of placing many definitions in a single helper file...

For example, I have the following helpers that dont seem to warrant a file per each.

Ember.Handlebars.helper('format-markdown', function(input) {
  return new Handlebars.SafeString(showdown.makeHtml(input));
});
Ember.Handlebars.helper('format-fromnow', function(date) {
  return moment(date).fromNow();
});
Ember.Handlebars.helper('format-long', function(date) {
  return moment(date).format('MMMM Do YYYY, h:mm:ss a');
});
Ember.Handlebars.helper('format-currency', function(mynumber) {
  return numeral(mynumber).format('$0,0.00');
});

im porting from a ember proj where everything is lumped into a few files. which is grossly too few.
