dfc.batch_hint_size limitation of 1000

I've written a custom migrator that creates an instance of doc type A (target doctype) from an instance of type B (source doctype). I've hit the dfc.batch_hint_size=1000 limit on processing objects whose objectIDs are returned by a query. Is there anyway around this limitation in a DFC based java app? I previously wrote (DFC 6.7) some code that had 2 loops. The inner one would work on 1000 objects at a time, while the outer one would pass in the next 1000. Does 7.2 DFC provide a means around the 1000 object limit?

Thanks,

Pete
