I just have to ask - how many records are in your source table, and what kind of performance are you getting out of your Analytic View? What target performance are you working towards? And are you developing for training purposes, a proof of concept, or a production scenario (or something else?)
The idea of "copying and pasting" data from one table to another is a really bad idea for a production solution. If you have a reporting requirement that's definitely limited to a subset of data then I'd recommend putting filters in your models which should definitely speed up your queries without data integrity/quality issues you'd face with partial duplication of another table.
