SS3 - feature definition back to XIN file


I am in the middle of project with  InRoads SS3 implemented. For some reason I have to complete the project with SS2 release. I left my xin behind when moved to SS3 on previous project  and created rich dgnlibs with element templates and feature definitions. Based on these dgnlibs I created template library where I used feature definitions from dgnlibs. 

Now when I need to go back to SS2 I have to update templates in my *.itl file with points' and components' styles. Is there a way to export feature definitions form dgnlibs to surface (components and points) styles in xin file? Some kind of linking dgnlibs to xin file? It is a lot of rework to do it manually.

Thanks you,
