Is there a way to history reports? So I can call past reports in the future?
Either design the reports so that they reference a variable timeframe so you can reproduce them when needed, or you can schedule them for exporting to a PDF or other format under the report configuration page.

Supply all criteria needed in the report via parameters, and only otherwise reference unchanging data (like tag history). Do not use now() or any similar timing function inside the report. Do not reference any current tag values.
This makes the report behave like a “pure” function. Give it the same parameters, and you get the same output.
Otherwise, saving the PDFs (in a database, perhaps) is the best you can do.
