LARGE pack and go

I'm trying to pack and go a large assembly, including drawings.  In the process, I also have to rename a lot of parts and assemblies.  So, after spending at least 2 hours getting the names the way I want them, I started the pack and go (including drawings).  2 hours later, it was still spinning.

I hate to keep trying this, because I spend so much time renaming parts and assemblies first.

Suggestions? (SW 2016)
