When I hunted in pre ban days we had marshals who saw us crossing roads and opened field gates for the non jumpers. the drove 4x4 vehicles. The knew where hounds would be drawing and so stationed themselves around that area.Even just marshalls would be of benefit! Although as you say, that suggests someone can provide the route to be taken in order for them to be far enough ahead to do said marshaling.
It could be done then so I am sure that it could be done now.
