There have been requests for SCP to include more options for arrival vectors. One is to allow the mission designer to select a region around the wing's placed location, so that they don't always appear in the same spot, but aren't bound to any specific object. Another was to add more vectors, augmenting from the current "in front of ship" option, with "behind ship", as well as top, below, right, left, and perhaps a more of a degree direction-based system. Something like:
Arrive near "GTD Bastion"
225 degrees (relative to target ship's lateral axis, so about 45 degrees from the back of the ship, on the left side)
125 degrees (relative to target ship's vertical axis, so about 45 degrees above the back of the ship)
600 (distance from ship)
There's also the possibly of incorporating variances into these figures, the same way that respawn delay has an option for non-absolute timing. Add an option for degree variances for both figures, and a distance variance. Granted, this can get rather extensive. This is just my own speculations.
