Export Style Sheet With Report

Hello

I cant really find an answer to this question so here goes.

we have a structure 

Product->Version->Groups->1->report1

Product->Version->Groups->2->report2

Product->Version->Groups->3->report3

Product->Version->Standard->Styles->Delta.jrtx

When in Jasper Portial and we export report1 it has a reference to theuse the Delta.jrtx style sheet.

Is there any way to get this to export in the zip that is produced?

Many thanks
