[AS] Making "keep overrides" the default graphic layer option for all placed graphics?

Question

If I relink thisLink when it is missing, and update link option was set to keep overrides, everything is fine. But if it was set to application settings, I am in a world of hurt, because suddenly all my Unit numbers will show 1-32 piled on top of each other (all layers visible in Photoshop) or the wrong one (just one layer visible in Photoshop) or nothing at all!
The catch-22 is that until I relink missing links, update link option only shows "unknown" as the result. Arrrgh?
set myLinks to every link whose status = missing
repeat with thisLink in myLinks
    get update link option of graphic layer options of parent of thisLink
        -->Returns "unknown" instead of "application settings" or "keep overrides"
    try
        set update link option of graphic layer options of parent of thisLink to "keep overrides"
        relink thisLink to newLinkPath
        update thisLink
    on error
        -->This always errors on the set update link option line
    end try
end repeat
Anyone know a way around this or should I just change my name to Yossarian?
Thanks in advance,
Eric.

Well, I give you points for creativity! Unfortunately, relink is destructive and overwrites any info with the default (which in CS2 is application settings).
What really kills me is that InDesign has some Sooper Seekrit internal list that only the Links palette knows about. So if you *manually* try and relink the document and then revert it, it automatically relinks against all the paths you've tried since launching it and therefore, the second time all the links show as linked and the process is non-destructive, unlike the "relink" command.
Argh.
I will think on it some more though. Thanks for your input!
PS: Adobe apparently broke the ability to relink against a string in CS4 from what I can tell. In spite of the fact that the dictionary specifically lists alias or string or string (yes, says or string twice in the dictionary), only alias really seem to work.
So...
set newLinkFolder to "" & path to home folder & "Pictures:"
set newLinkPath to newLinkFolder & name of thisLink
try
relink thisLink to newLinkPath
on error
display dialog "FAIL!"
end try
try
relink thisLink to newLinkPath as alias
on error
display dialog "No fail. You'll never see this message!"
end try
