I have a main ASM1 that resides in a detached drawing.  The detached drawing also contains, ASM2.  ASM2 is a contrived asm that I created to show something.  So, ASM2 doesn't reside in ASM1.  Is it intended behavior if I Pack and Go ASM1, which includes the detached drawing (detached drawing contains ASM2) to not move ASM2 into the new location?

Why do I think this is a big deal?  I did the above to my main ASM1 and was testing out 2019.  I opened the detached drawing in 2019 and some of my originals were made future version...And to top it off 2019 does not work with my files.
