Complex Operators with custom inputs (eg modulo)

I am looking for a way to implement a modulo operator, but I am not sure what might be the way to do so.

When selecting the modulo op the resulting rule should display something like this (please ignore the first and last select, the image is taken from the current implementation):

The idea is to model operations like:

field % value = 5
field % value > 10
....

I've been able to add the modulo operator but all the fields are now shown as inputs for numbers:

(function() {

  var QueryBuilder = jQuery.fn.queryBuilder,
      operators = QueryBuilder.defaults('operators'),
      operatorsAsArray = Object.keys(operators).map(function (key) {return operators[key]});

  operatorsAsArray.push({
    type: 'modulo',
    nb_inputs: 3,
    apply_to: ['number']
  });

  QueryBuilder.defaults({operators: operatorsAsArray});
})();

Is there a way to specify custom inputs or a template for an operator?

Start with the operator registration shown through QueryBuilder.defaults and trace how nb_inputs and apply_to determine the rendered controls. Inspect the operator UI handling to determine whether custom inputs or templates are supported, then verify that modulo expressions render and preserve the intended field, value, and comparison controls.
