Hey, everyone! I'm trying to figure out how to use the tag mapper tool in Calibre. I'm confused how this works, and didn't see anything about it specifically in the Calibre documentation.

First question: Does the tag mapper have to run as a process at ebook file import, or do the tag mapper rules take effect dynamically after I create said rules?

Second: Is this the correct setting to split the tag "Young Adult Fiction" into the two tags "Young Adult" and "Fiction" or am I misunderstanding things? I'm assuming the use of a comma denotes a second tag?

Thanks for the help, friends. Hope you're faring well in this wacky world.
