Don't Trigger on Fast Moving Objects?

[Ethrex]

On a camera I have mounted outside, flying insects and sometimes dust triggers the motion detection. If I paint rectangles I can see Blue Iris is detecting the objects well, but the objects are moving at super-human speed. I think I could prevent the camera from triggering on these uninteresting motions if I could just instruct Blue Iris to only trigger when an object moves "at most" X speed. Is there a way to do that, or maybe put in a feature request?

Thanks
