Rules on requests:
✔ 1) You may request additional subgroups to be added, if they are used by your vehicles and may potentially be useful to other mods as well.
✔ 2) If new subgroups are created in your mod, you are welcomed to post the details of those subgroups here. There is a maintained list of all known subgroups. So your details will help minimizing conflict with other mods!
✘ 3) You may NOT request assigning any modded items here. I leave the decision to their authors where they should be placed. Please go to mod page of your favourite mods, and make your request there. Please see my policy.
