WE NEED THE ABILITY TO DO A LEFT JOIN WITHIN THE SISENSE DATA MODEL

I'm also struggling with the limited flexibility to customize joins, particularly in tables. The workarounds described in this thread are functional but they are cumbersome, time consuming, and inefficient. The functionality of the software would be much improved if there was an option to include all values from a particular column even if there are no corresponding matches. 

For what it's worth my specific use case involves showing a count of items per a given timeframe - we need to see zeroes instead of gaps in our data.
