How would I go about "flagging" units as mercenaries? I don't want them showing up in taverns or anything, I just want the increased mercenary cost. I tried adding them to the troops document in native before the mercenaries_end entry, but that just jumbles everything around. I usually use morpgh's editor but that adds units to the bottom of the list.
Sorry for an easy question that's most likely has been answered before several times in this topic.
