Is there a way to return to Manual Sales Tax settings?  This Automated Sales Tax setup is terrible!

For example, when one sets up the Automated Sales Tax settings, one is forced to choose an agency from what is listed there.  I cannot create an agency from scratch.

So I did what the QB agent told me to do and chose Illinois Department of Revenue. But I don't remit taxes to IDR - I remit directly to the municipality.  Can this be undone?

What happens if I choose "Make Inactive" on the Tax Agency currently selected?  Can I then start over and create my own custom agencies?
