Sonata Admin Bundle - Form type: sonata_type_collection - custom template?
===

Is it possible to override the template for the form type: "sonata_type_collection"?

Ive tried along these lines:

    $formMapper->add('slides', 'sonata_type_collection', array(), array(
                    'edit' => 'inline',
                    'inline' => 'table',
                    'sortable'  => 'priority',
                    'template' => 'MyBundle:Form:slides.admin.html.twig'
                ));

but to no avail.

I know I could override the entire template, but I only want to do it for this form, not all the places where I use this form type. 

Does anyone know if this is possible?

Thanks
