You can import into multiple folders. As long as the folders are listed in the rebuild database folder list then the BookIDs will be continuous.
If I understand you correctly you want to have seperate songbooks for each folder. When you get ready to create your songbook, remove all but the folder you want to create the songbook for from the rebuild database list, rebuild the database and it will contain only those songs in that folder. Then create your songbook. Go to the songbook folder and rename the file to associate it with the folder and also keep Hoster from overwriting it. Change to the next folder in the rebuild database and repeat until you have created all of the seperate songbooks. Then re-add all the folders back to the rebuild database list and rebuild again so Hoster can find all of your songs when you want to play them.
