    MBWATSON Sure, in the Modeling tab of your ribbon, choose New table (in Report view) then just use the formula:

MBWATSON Right, so that isn't going to work in the slightest. Power Query loads data and then DAX calculated columns are created. So, the columns don't even exist yet when you are appending the tables together. You can either add the DAX calculated columns to the appended table, or create the calculated columns in Power Query before appending or you could skip appending in Power Query and use a UNION to append the two tables together in DAX.

Greg_Deckler thank you for that information! Nothing that I have researched has mentioned using Union in DAX. I will attempt it and let you know how it goes.
