Boston Bowel Preparation Scale

We are working with a customer with an endoscopy solution. Currently we are making model for the Boston Bowel Preparation Scale : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2951305/
I did find any archetype for this? Do you have any knowledge of such an archetype?
Want to join a session discussion the modelling of this score?

I have created an initial draft for the archetype here: https://tools.openehr.org/designer/#/viewer/shared/Pz9zaGFyZWRJZD0xJDYyZmQxZGYyY2JjNTRiMDJiMjc2NDBlMzc5MDFhMTZk
