Conversion Tracking Multiple Accounts

How do I track multiple (10+) accounts with the conversion tracker?

[Joe54]

Because of the number of our keywords, we need to use multiple (10+) accounts, which are then managed through an MCC.

Our site setup makes it difficult to get Google style analytics (tagging the destination URL) working accurately. We would therefore prefer a cookie based system like the one offered by Google's conversion tracker.

However, there have been reported problems with using multiple pieces of code (http://groups.google.com/group/adwords-help-roi/browse_thread/thread/a515c87b1b54ebb9) including slow load times and double counting conversions.

Is there any good solution beyond simply pasting 10 to 15 different conversion tracking scripts on the page?

We would like to use just one script and associate that (perhaps by passing in multiple IDs in a single variable) with all of the accounts. Something along the lines of:

...
var google_conversion_id = [12232,33222,44422] //[ID1, ID2, ID3,...]
...

Thanks for any help you can offer.

it IS possible to link multiple adwords accounts to your GA account but this will require the help your Google account manager.
