Create Value Copy (?!) of Data Table

Hello there,

my project exists of 24 different queries (different countries, segments, etc) - which are subsequently combined to one "Mainquery".

These queries all represent the same month ---> "Mainquery" = One month, different countries/segments

Now I want this Mainquery over several months. My idea was to "value copy" the Mainquery, adjust the 24 original queries and append the new Mainquery (new month) to the value copied Mainquery (old month).

I think that is not possible or rather I'm thinking too complicated....

Does anybody know how I can solve my problem?

Thanks in advance
