Just trying to navigate the new Logics Loop system

So, a little history. I had 44000 samples, roughly. some apple loops, some user. some on Mac HD, some external. we moved loops off the hard drive to format it for a backup on a friends CPU, when we replaced the files afterward, Logic couldn't find them all, had about 32000 remaining. now i updated to high sierra, and to Logic 10.4.1, reindexed all loops, and now im pretty sure its just down to 22000 factory loops. i would like to know how to reindex all my user samples into the same organization system as the apple loops again, i don't really care much for the untagged loops option. If anyone could help, it would be great, and i'm sorry if this is a dumb question, but i've scoured google for about 30 minutes and can't find relevant information past 2013. i'm happy to provide more info if needed, just ask,
