How to automatically add a new column from a refreshed table into a Matrix visual?

[jcso]

I'm connecting to a table from Big Query which is updated every month with a new column.
I would like to have a Matrix in Power BI just replicating that table, with all its columns, without having to manually select every single column into the Matrix Visual.  And just by refreshing the data source, the Matrix would be updated to. Better yet if the even the refreshing is automatic.
This is the first time I use Power BI and I'm struggling for the last 2 hours trying to find a how to on this. I guess it should be simple, but I have no clues on how to to it.

@jcso , I doubt you can add a column automatically in Matrix. If that is row value(Unpivot Data),  then it can add

hmm, thanks! I've found a different way to structure the data, to avoid having the need to add extra columns
