Automatic assignment of sounds for midi

Hello there, i was wondering if someone could help me clarify a few things regarding halion sonic se / halion 5 etc.

At present I’m working for someone who provides me with a bunch of midi files, the midi is opened in c7 of which each midi channel is assigned to the correct instrument sound in halion sonic se, halion se seems to pick up which is the most appropriate sound which is very helpful

however my client does not like these sounds and I’m wondering if there is anywhere else in halion se, or other halion products that lets me choose an overall different soundest without having to manually assign each one to a better sound?
