Yes, there is a way to add a DLL which has certain exports to do what is
needed to do.

This isn't the place to discuss this so let me point you to the IB-Support
list here at Yahoo Groups. Hope that you hear from Dave Schneppers. He is
very helpful in these regards. I believe he has been working on a kit that
should make it much easier for people to supply customized collation
drivers.

You might try IB-Architect as well.
