popup file for related table?

hi,

is it possible to configure a pop-up file for a related table?
(I want to rename some fields and hide the others)

I have created a pop-up configuration file for the feature layer and it work fine but I don't know how to do with the related table.
if it is possible to do this, do I have to call it in the main configuration file?
