Could you please clarify if you mean connecting directly to the local GPO editor (i.e. without establishing a connection to the remote Host machine first)? If this is the case, unfortunately, there is no such feature.
I apologize for my somewhat misleading previous reply.
Unfortunately, there's no separate connection mode for the GPO policy editing yet and we do not have plans for implementing one in the nearest future. However, you should be able to edit GPO policy via the Terminal mode or you can also establish a remote connection (using the Full Control and View mode or the RDP mode) to the remote Host machine and then edit GPO policy via GUI.
