Symfony: Field Collection, returning on selected value - forms

Question

I am using a collection with type field type. This is retrieving fields from a table. I am able to add/edit the fields.
What I would like to do is only return certain fields in the collection.
eg only the fields where the column reference_id = 2
The reason I would like to do this is because I am grouping the returned values to their group.
So I will be returning multiple collections grouped by their group.
DetailsType.php
$builder
->add('FieldText', 'collection', array(
'type' => new FieldTextType(),
'prototype' => true,
'allow_add' => true,
'allow_delete' => true,
))
FieldTextType.php
$builder
->add('label', 'text')
->add('value', 'text')
;
Edit - Added the type
DetailsType.php
class VillaDetailsType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('CollectionOne', 'collection', array(
'type' => new FieldTextType(),
'prototype' => true,
'allow_add' => true,
'allow_delete' => true,
))
->add('CollectionTwo', 'collection', array(
'type' => new FieldCheckboxType(),
'prototype' => true,
'allow_add' => true,
'allow_delete' => true,
))
;
}

$resolver->setDefaults(array(
