Is it possible to cancel a scene before it starts?

[Mikarun]

One of my installed mods, Paradise Halls Home Sweet Home, triggers a SexLab scene between a follower and a PAH slave if the follower's arousal exceeds a certain number. I like the feature and want to keep it enabled, but sometimes the scene appears to get stuck because the actors are too far apart, and my only recourse is to reload. It would be really useful to me to be able to cancel all running sexlab animations or at least all of those involving a specified actor. Is this at all feasible? I know Scent of Sex can cancel all the scenes it's kicked off, but that might be because it's doing something special to them.
