Database View In A Web API

I'm trying to expose a view from the Appian DB via a Web API. 

The Web API requires a Data Store Entity Constant. So I try to create a constant with a Data Store Entity type, but I need a Data Store Entity created with the View Data Type. I create the view data type without issue and add it to the Data Store but it will not save and publish (I get a 'Appian.vwMyView' is not of type 'BASE TABLE' (APNX-1-4178-000) error). Also I do not want the view created as a table as it is already created in my DB as a View. How would I add an existing view into a Data Store?
