Limit row count in report viewer using Alarm Journal Query and Tag Historian Query Datasources

It would be great if we can limit the row count of report's data dynamically in report viewer component in runtime. The datasources Alarm Journal Query and Tag Historian Query with sample size of interval are not capable of limiting their row counts. It consumes a lot of memory if there is a huge amount of data in runtime especially the Tag Historian Query with interval in reports which will cause the client to freeze and crash

You should be able to achieve this with a script data source that limits the rows returned. The docs (https://docs.inductiveautomation.com/display/DOC80/Scripting+Data+Source) have examples of how to alter other datasources.
