Organize drawing substitutions

What is the best way to organize drawing substitutions for rig that has not only many different drawings for each body part but also different outfits.

Should I use use symbols maybe, as the toon boom guides recommend symbols for character outfits.

Or maybe a combination of symbols and substitutions if that is even possible.

You can use "quickswap"script released by cartoonflow. It’s really helpful to manage drawing substitutions.
