You route all affected tracks to a group. You export the groups, not the tracks.
For example, I do this with VSL instruments when I have a large number of automated articulations. I can have some really complex routings that are playing a really simplistic melody line because of the number of articulations and automations+FX on those particular articulations. So, I route downhill to a lot of group tracks that I keep in a “stems” folder. When I’m ready to export for mixing, I dump them through those groups.
