WebReports and Device "Created Date"

Is there a field (or fields) within Web Reports that could be used to identify the date a given device was initially created in the database.

The objective is to use this field to distinguish devices that have been in the database for some time from those that have been recently added (new devices).

Using a “Build Date” or “OS Build Date” field is not reliable as it cannot separate out new devices from rebuilt devices.

You can create a property with relevance similar to subscribe time of site "actionsite", then leverage this property within Web Reports. See Relevance for client “registration date” with bigfix for reference.
