ScreenConnect Devices connected within the last 30days

Hi,

I have lots of requests for device audits. What we do see is, when we run the report for a filter group we get a lot of devices that were never deleted / uninstalled for numerous reasons. So when we run the report we get hundreds of devices when the filter group may only have 60/70 devices. So lots of cleaning up to do. 

Is there a way to completely remove these older machines from the database? Or be able to filter devices that have connected back to the ScreenConnect server in the last 30 days. Could use a filter for device checking <=30Days? 

I have clean up rules to drop devices older than 30days so they no longer show in the filter group. So why can't we do this in reports?
