Hi Andrzej,
depending on how your data is ready to be linked I suggest to use a join oir union in the queries pane:

Keep in mind that if both queries return measure values, a join works only if both queries return data on the same grain level. You have to set the right cardinality depending on your data:

And at least: if you need those data combined together many times I also suggest to create a Framework Manager model or a Data Module where all these data modifications take place.
