I understand you are trying to point towards the structures as you pass them. Keeping with how orbit works, nose in. However, pole 24 would end up being your ROI as it traveled even as flown elliptically
What you'd need to have is the copter follow a line, with the line being the ROI, for an auto mission like a Survey. Setting a distance parameter from the line. Anything can be done, but you'd need to program what you are asking to follow the line. The dev working on MP, Michael Oborne, could be contacted for such a feature request. I could see it as a useful tool and it would seem relatively easy logic setting up...just need to understand coding...
You could program a mission in MP/Tower to fly an odd rectangle and have it point 90/270 degrees of the flight path (yaw_angle I believe). Give that a try, if it works then it could be implemented into a mission as an auto task...
