ERSPAN on Remote Probe

Using a 1000v with ERSPAN successfully for our packet traces and captures. We're now transitioning to Virtual Probes in our environment. I've not seen a setting that allows me to apply either an ERSPAN ID or set an IP address that will be recognized by the eth1 interface on a remote probe.
Is this possible to use ERSPAN?

ERSPAN encapsulates the traffic in generic routing encapsulation (GRE) and is, therefore, routable across a layer 3 network between the “source” switch and the “destination” switch. However, LANGuardian does not have a decoder for GRE so it cannot be set as a destination for this traffic.

It may be possible to route this traffic to another switch and then use a standard SPAN port to send the traffic to LANGuardian.
