Maybe it's impossible using the IBO internals, but a bit of imagination
normally solves impossible things.

For a lazy programmer like me, the simplest solution seems to be to make
the criteria match, which at least should be possible the following way:

1) Create a new field in your table and a new generator. If you want
indexes to be used you should probably add an index for (<newfield>, <pk>).
2) Grab a new value from this generator.
3) Add to your LIST_QUERY something like 'OR <newfield> = <grabbedvalue>'
4) When inserting through ITEM_QUERY, set the new field to the value you
grabbed

That's it. Now every record you insert will match your criteria!
