Is there a way to know if an id returned from Gst-nvtracker is a new id or previously identified id

When using Gst-nvtracker(either NvDCF or DeepSORT) in deepstream, we get a new id for each new person in the video stream.

We have a requirement where we need to know if an id is generated for the first time.

Is there a way to know if an id returned from tracker is a new id or previously identified id? Without comparing with previous data.

Please provide complete information as applicable to your setup.

Seems no. Is it possible to check it in application with one probe function?
