Due to the lack of answers I take it there is no way to accompish this in ISA?

Well, we have some applications which seem to be having problems when they have 
to work through ISA's proxy. Obviously the correct solution would be to apply 
pressure on the vendors to fix their software but since this is missing 
critical stuff I'd like to explore other alternatives as well. Most of this 
software runs on AS400 and we are somewhat stressed for alternative suppliers, 
mainly because of long time and long term relationships with those vendors.
