Is it possible to copy "missing" kuids

[nahgallaco]

I have missing kuids in TS12 which are no longer on the DLS but which I have in earlier versions of Trainz.
Is it possible to copy the old kuids into TS 12?
If so how do I do this? Is it simply a drag and drop operation?
Where do I find these kuids in my computer?
EG. The beaut Clinchfield mallets work fine in 2009 but show missing kuids when imported into TS12. These kuids are not missing in my 2009.

Save to cdp using 2009 CM and drag and drop to TS12 Content manager.

If you highlight all the missing ones you can make one cdp out of them all which is quicker than doing it one at a time.

Some of the missing ones might be built-in to 09 or they have been updated and are not infact missing.
