Adding Fasteners to the assembly or patterning it.

In case of two parts bolted together in the assembly butthere holes are made separtly
in the part Environment. when i try to do the smart fastenercommand sometimes it's not work well specially when the addingbottom stack. So i have to do it manually some times by grabbingthe bolts, nuts & washers from the tool box and add then by myself. which take more time than it has to take. Could any one findany solution for that.SolidworksAssemblies
