Using table as a feed for a new query

Hello, I have some data loaded in power query which I have shaped and fed back to a table in powerBI. Once there I have applied some DAX. I now want to use that table as a datasource to feed it back ...

    Yeah, this workss nicely. Good thinking. 

     

    the why is that my ragged hirarchy has a top level of 2500+ with a near exponential rate through 12 generations but still growing. I tried using a power query function but it cycled through one record at a time. I tried using DAX to do a calculated table of what i wanted to do but the calulation time was although much faster, still too slow. Using power query to split and unpivot DAX results based on =PATH & =PATHITEM is about 22 time faster than the calculated table method and literally 100's of time faster than the custom function method.
