Theoreticaly, you can have levels and soldier bonuses on such commendations with something like
commendations:
- type: STR_MEDAL_ORIGINAL8_NAME #original team
description: STR_MEDAL_ORIGINAL8_UFOPEDIA
soldierBonusTypes: [STR_MEDAL_ORIGINAL8_NAME, STR_MEDAL_OG8_SUPER_MEGA_MAN]
sprite: 4
missionMarkerFilter: ["THAT_ONE_MISSION_MARKER_NAME"]
criteria:
# v-- first level not achievable by normal means, but already awarded to manufacture/event created or starter soldier
totalMissions: [100500, 1, 1, 1, 1, 1, 1, 1, 1, 1]
# ^-- instant level 10 commendation
but OXC prevents this for Original 8, probably unintentionally.
