Dynamic Products

I have the need to modify what products to charge depending the answers of a form, so I hide and show products on demand, what i notice is tht this plugin dont pickup any hidden attribute, and if after the form is displayed and before the submission i product is showed depending the answers the plugin doest pick it up.

Is there is a way to do the feed with hooks? or triger the products search with gform_after_submission or other similar?
