I see that it is possible to make additions to the options of the dealtype in the property settings on the website. However, I seem to be unable to make additions via the API. I tried doing a PUT (the only action available) but got back an error response: The Property ‘dealtype’ has a read-only definition, and can’t be mutated. Am I doing something wrong or is it not possible to add to the options?
I checked the “properties” of this property and have this set: “optionsAreMutable”:true.
