Adaptive / automatic-scaling Search-Area for Tracking-Markers

The pattern-area of the track-marker scales according to the movement of the camera (if the camera approaches the tracked area, it becomes bigger). But unfortunately the surrounding search-area doesn't scales correspondingly, instead stays fixed - see attached screenshot. This becomes an issue, because by that the tracking stops and the user has to scale the search area manually. So I would suggest an option "Adaptive Search-Area".
