Unpivot column into NEW table?

I have 6 columns I need to unpivot into a new table.

I cannot seem to figure out how to do this in Power BI Desktop.

I can unpivot, but then it duplicates all the rows of my existing table as I don't want to make the existing table change.

Is there a way to select columns and unpivot them into a NEW table (and specify a FKID to go with them from the original table)?

Is there an M language command I can use to generate a new table and populate it with the results of an "unpivot"?
