-- [ ] Move submission types from config.yml into database.
+- [ ] Migrate the parser.sub dictionary to pydantic models.
+- [x] Move type_decider to metadata based method rather than excel map.
 - [x] Solve bug for plate mapping when two samples of same name are in different rows.
     - Try importing "L:\Robotics Laboratory Support\Submissions\Wastewater\2023\2023-06-21\RSL-WW-20230621-1.xlsx" for example.

 # set out the workflow I've imagined for creating new submission types.

+# The workbooks no longer need a sheet map, but they do need their submission type put in the categories metadata of the client excel template.
 # Second, you will have to update the model in backend.db.models.submissions and provide a new polymorph to the BasicSubmission object.
 # The BSO should hold the majority of the general info.
 # You can also update any of the parsers to pull out any custom info you need, like enforcing RSL plate numbers, scraping PCR results, etc.
