I want to give fabrication drawing for shareable parts also in the same panel assembly so that all the panel part fabrication in one set. Is it possible to do that or we have to create assembly for each and every part of the panel. If 2nd option is the only possible thing, then can we make selected sheets in one set so that all the drawing sheets belonging to the panel and its parts are kept in one place. This would be very helpful as I have more than 20 types of panels.
