What you do is you arrange all the open SOS to where you can see the coordinates on your screen, then hit print screen to save it to your clipboard (you can probably put about 40 or so into one image).
Save the image in an editor, or print it out on a printer.
Go to the above link, input the coordinates; this will convert the data into UOAM/UOC map data. Copy the yellow column info (for the rows you entered data into the blue area), and paste it into an existing .map file (or copy & rename an existing file, and paste over the data).
Repeat as needed.
Don't worry about overwriting the data - just don't mess up the formula calculations.
Doing this in batches cuts the time by about 50-90%, especially if you are doing it from a printer or split-screen (having to switch back and forth between the image editor and the browser is a bit harder). Of course, getting someone to help in the same room on a different computer is good, too (one person reads off the list, the other types the data).
