# Request Specific Flag - Da Vinci - Documentation Templates and Rules v2.2.0

## Extension: Request Specific Flag 

If this flag is 'true' then a distinct QuestionnaireResponse is needed for each request where that Questionnaire is solicited. If false, then a single QuestionnaireResponse can be used across all requests where the specified Questionnaire url and version was solicited. (i.e., You can fill out the form once and re-use rather than completing multiple times. Typically, re-use of a form is limited to the scope of a single encounter)
