Is there a way to save an assembly as a PART file while preserving the individual parts history and features?

I tried doing simply save as, all bodies, but I still lose all of the hole wizard information for 10 welded brackets on my square shaft. I also have two square to round adapters pressed in to the ends and want to preserve the sketches without having to keep it an assembly. Thanks for any help you can offer!
