Joomla Jomsocial Module Hellome Tweak for facebook

tweak the module HelloMe from jomsocial when it comes to facebook connection. The module after login or registration directs the user to main website jomsocial page. I need the module to, after successful login or new registration redirect user to my facebook app canvas page Now the process is: facebook canvas - press Login or registration facebook button - user ends up outside the canvas in my main jomsocial page What I want is: facebook canvas page - press login or registration facebook button (user logs in or registers in my website) after successful login or new registration - user is redirected again to my facebook canvas page My facebook app canvas page is hosted in my website inside hidden menus with a special template 520px for facebook. If possible would like an option in the module backend xml where I could select the menu (from all available menus) where to redirect user to. Will accept best offer.
