Im not sure about Enigma2 images, On my DM600 I can use a combination of USALS + stored positions. I used this for a week or two after a storm moved my kit out of alignment.
To do this, I sent the motor to the desired bird using USALS, then go to the motor setup page, use the menu to move the dish east or west till you get a the best signal you can. Then hit the button to store the position. (Green I think).
When you come back out of that menu, you may need to re-enable USALS. When you now select that sat, the motor will move to the stored position rather than the calculated one. (It does on the DM600 at least)
Hope this helps
