Deactivate Tracking-Token

It would be great, if there is a possibility to deactivate the tracking-token. Until now, when I give away a tracking-token for an event so that multiple people can track, i can't redo this anymore and people can track on my server until I remove the session. But moving all the devices to a new session also changes the public watch token and I have to give away the new watch token everyone who wants to see thos session. (I use your Software to track our rowing-boats on trips, so that the participants' parents can watch their children)

That's why I suggest to add switch like the switch for enabling public sessions to enable the tracking token.
