I have several huge source table (>20 GB) , and I need to create new table with unic values from [Column 1].
I create new query with List.Combine(Table1[Column1], Table2[Column1]) and several transformation. After Apply changes, PBI upload source tables several times: for main data and for created lists.
Is it possible to reduce number of uploads source tables?
As a source of raw tables I use dataflows.

@Denis_Slav , yes, but Power query kind of works on the complete table. so once you are done with all data modeling you can try this.
