Auto Add with multiple libraries

I have two libraries and would like them to auto-add from different folders. Is this possible?

I don't believe it is as auto-add seems to be global so failing that how about library A auto-adds and library B doesn't?

If I can't do that I'll have to turn off auto-add which I really don't want to do.

If I do have to turn off auto-add is there a way to make importing from single directory a one-click process?

Advance Thanks

ps. if there's an existing thread I couldn't find so feel free to point it out.
