Mass import gen 8 Database into Sword save?

[james9120]

I'm trying to figure out how to mass import the gen 8 database I downloaded from here. I can import the Pokemon 1-1 by dragging and dropping the PK8 file into the Box, but that'll take forever. When I load up the Tools - Data- PKM Database, it loads something like 1000 Pokemon I did not download. I'm just trying to use the database I downloaded from the files available here. 

 

Any advice? Thanks
