Is there a way to save parts internally in an assembly?

It makes sense to save parts within the assembly documents oncertain projects were the parts will never be used again for anyother assembly; e.g hot tub skirting pieces when my primarybusiness is actuators.

Saving a part in an external file when working in an assembly seemsto be an irreversible process. Once a part has been savedexternally, is there a way to again save it internally?

Thanks is Advance
