adding externalize domains in url (content/dam) exposed via XFragment

Hi,

is there any way to append the domain url into the (content/dam) url value which is exposed via XFragment.
- I have 2 Content Fragments (which are overlayed by OOTB contentfragmentlist) dropped into an XFragment
- now I need to append my domain url to the (/content/dam) value which are exposed by the XFragment by using the exposed values of XFragment in the from of model.json in order export the content to another domain.
