Rolling back a set of change sets

We do database releases which are made up of a group of change sets and our database change logs are organised in the following way

MasterChangeLog.xml

              —> Release0001.XML
                       —> AddCustomerTable.XML
                       —> AddOrderTable.XML

              —> Release0002.XML
                       —> AddNewColumnsToCustomerTable.XML
                       —> AlterOrderTableXML

              —> Release0003.XML
                       —> AddPreferedCustomerTable.XML

I would like to know how I would go about rolling back a set of change sets. I was hoping that I could use tagDatabase with the release number (Release001, Release002 or Release003) and just roll back using the tag

I would expect to be able to do something like this if I wanted to rollback all change to Release001
java -jar “liquibase.jar” --changeLogFile=“MasterChangeLog.xml” Rollback “Release0002”

Could you please tell me how I would go about getting this to work with Liquibase?

Thanks
