Replicate a node with field collections but not all field collections

Hi,

First of all, thanks for the module, it works with no bugs.
I have a content type with 12 field_collection fields and when I replicate a node I need that just 5 of this field_collection fields to be replicated on the new node.

Could you tell me how can I implement this modification?
I read the replicate.api.php file in 'Replicate' module folder and tried make this but no success.

I'm using this modules:

Replicate 7.x-1.1,
Replicate Field Collection 7.x-1.1 and
Replicate UI 7.x-1.4

Thank you
