Question regarding altering sort collations - Saxon8

I am using Saxon8 in an application sorting indexes, glossaries and the like
for 18 languages. Generally, the default collations performed by Saxon via
Java work fine for us. However, I need to make a minor change to the collation
for DA. I need to remove the digraph "AA" from the ordering.

Is it true that I need to some how modify the underlying Java code to do this
or is there a way, from the stylesheet, to override the collation just for
this one language? If Java, is there a location where the standard collations
are placed that can be modified.
