Can I save an assembly or drawing so it will not ever rebuild in the future? I have a lot of problems with SW rebuilding assemblies with the wrong fasteners and losing important information.

Is there a way to prevent an assembly from ever looking up referenced parts again, or can you do some sort of internal pack and go. Like if I could make the file contain all the relevant reference

items like screws and washers internally then in 5 years if I open that assembly it will be right even if I've changed my parts library.
