In my experimentation, where the target circle appears depends on two things.

The first is where you're camera is pointed. Fire the ability, turn the camera, and fire it again, and the target circle appears in the same line of sight. You can adjust this by moving the circle by holding L2 and using the left stick, but the game remembers this, and next time you fire the ability it will use a combination of your current camera angle and you last target position adjustment.

You could try using R2 + Left Stick to set a comfortable position for the ground target marker, and to actually target the circle, move the camera each time. If you wanted some extra precision you could place a HUD element over your preferred targeting position so you know which direction to look in before the ability is fired. So long as you don't move the circle again with the R2 + Left Stick combo, it should appear in that spot every time until you're logged out, I think.
