Topic: SDC Questionnaire.item.code defining

I'm working on a project which have several Questionnaires which ask questions like?
What is the Patient continence which corresponds to Finding of bowel continence Code: 300387008 (System: http://snomed.info/sct)
or
What is Learning finding Code: 106138009 (System: http://snomed.info/sct)
I understand I would use item.code to point the concepts, use item.type of reference and also use extension http://hl7.org/fhir/StructureDefinition/questionnaire-allowedResource (using STU3) to specify Observation.
How would I specify more details about the Observation. I think the answer is R4 ObservationDefinition and this links to a ValueSet?
The ObservationDefinition.(x)ValueSet would have a SNOMED ecl which looks like:
<<300387008 |Finding of bowel continence Code|
<<106138009 |Learning finding|
If my Observations don't have a valueCodeableConcept, the link to ObservationDefinition still works. So I'm thinking I need to create an extension on Questionnaire.item.code which links to a ObservationDefinition (unless one already exists?).
I'm also tempted to add an extension for ObservationDefinition.validCodedValueSet and ObservationDefinition.validCodedValueSet which gives a hint to the SNOMED ecl query (to avoid multiple calls and also be used to auto generate the ValueSet).
