There may be other ways, but I would likely try:
- Create the pipeline with the Google Analytics through to File Writer.
- define variables for AccountID and TableID
- set Account ID and Table ID to expressions (clicking the = button) and map them to their respective variables.
- in the File Writer, set File Name to an expression and map it to Table ID.
- Create a second pipeline with CSV Reader and Pipeline Execute
- create a csv file to store all account ID-table ID pairs.
- in Pipeline Execute, call the first first pipeline and map the CSV header labels to the Account Id and Table ID variables.
- run this pipeline.
