Custom horizon for ground stations

Enhancement request - I'd like the ability to specify that some portion of the sky is blocked (in this case, by my house), so that automatic jobs from other users will not be scheduled if the satellite will not be visible to the station on that pass (due to being behind my house). Example: a DO NOT TRACK list that specifies my station is blocked in direction (N, NE, E, SE, S etc.) and max. Elevation (in degrees) in that direction. I recognize that this may not be practical to achieve.
