Yup, that's a BIG problem...

These are already filled in fields that you are merging? Will you
ever need to extract the data out (eg. export as FDF?), or just print
and/or archive?

You may/will probably have to use the low level CosObj calls to
change the actual dictionary entries on the form field annotation objects.

Bad assumption! PDDocInsertPages() doesn't do anything fancy -
it just copies all the relevant data...

Named destinations won't help. Templates are for server-side
processing, mostly. They MIGHT be usable here, not sure of your exact issue.
