Hello, Im operating large amount of tags in my project and every time I need to change a bunch of them, I use export/import tags, editing a corresponding csv. But every time, I import it “max time between records” resets to unlimited. From a manual its apparent, that there is “HistoryMaxAgeMode” and “HistoryMaxAge” columns somewhere in SQLTags Historian system. So how can I save that properties to csv, where can I check that columns in Ignition, and what values should columns have for each of possible modes. Thanks.

This was an oversight - it has been corrected for 7.3.3.
