If there's a finite list of types, you could use message selectors on your consumers to partition certain types to certain groups of consumers. It won't be as dynamic as message groups are, but if the possible types aren't dynamic then that doesn't matter anyway. Just be aware that message selectors can have a performance impact (which is often negligible but can be significant), so make sure you measure how much impact this change has on your performance and adjust accordingly.
