Report - Retreive Historical Tag Values Greater than X

I was looking to see if it’s possible to use the “Tag Historian Query” in the report builder for a tag, but only retrieve values for the tag that are greater than X. We’re trying to get the average flow rate over a shift, but only want to use flow rates greater than 1 i.e. only when something is running. In a SQL query this is easy, but I wasn’t sure if it’s possible to do it on historical tag values.
