A large publishing client asked us to implement something similar to what you asked. We crated a database table to keep track of successful sessions within a workflow. Each session will have a mapping at the end that adds an entry to database which says I passed or failed. When we try to run in a recovery mode we query the database at the beginning of each session to find out if we need to run this session or not.
We also provided a web interface to this table where business users can manually choose which session to run or escape based on their needs.
