In FDI out of the box, a few date dimensions are supported. For example, in CX - Sales (using Salesforce source) in the subject area "SF - Campaign Members", FDI supports proper date dimensions against 4 dates — SF Campaign Created Date, SF Campaign Start Date, SF Campaign End Date and SF Lead Created Date.
We need one more that is based on the Campaign Member Created Date.
What is the best way to achieve this using the Semantic Model Extension tool?
