dbo.Evt_NS_Client_Config_Request - Keep Longer Than 1 Month

We use the dbo.Evt_NS_Client_Config_Request table as the source of when the last time the computer was active in our environment. This seems to work well in our case, except for the fact that this table only holds 1 month of data.

I looked in the Resource History section on the NS (Settings\Notification Server\Purging Maintenance) but I dont see a way to alter how long this data is kept without being purged.

Does anyone know of way to keep this data longer, or are you using a better dataclass/table for information on when the last time your device was active?

I appreciate your time.
