How to update Observation Types by using Import Anything in Confirm

Product Feature: Application Infrastructure
A user wishes to update the Observation Types for ‘Column Condition’ and ‘Bracket Condition’ conditions on a feature, by using an import anything file. 

Which is the best template to use? The only specification which seems to list this is for ‘Surveys’, however this also requires an ‘External Ref’ and ‘Version’ before it can run and, as this is not updating from a survey, this information isn't available. 
To achieve this in the original file remove `Survey` data - in other words just run the import using 'Survey Section' (as a Feature identifier) and 'Survey Observation' from the specification.
