I've only managed to do it by adding extra boss details but using custom minions, LTs, or bosses who are set to not auto-spawn. You can use them for custom enemies but not if using non-customs (then boss spawns only allow bosses, for whatever dumb reason still).
I haven't seen this problem, but I think I have used multiple cookie-cut minions in a group. I play with the colours though, perhaps that bakes them in.

I read a guide here on the forum that suggested adding multiple enemies of the same type to get the ratios you are looking for. Such as 3 "Soldier" and 1 "Medic" all as minions.
Every time I add multiple minions of the same type with the +Add button it shows an extra copy, but the information is lost after saving.
If there a method to do this? Must I create an entire duplicate enemy called Soldier taking up plenty of % space in the mission?
Thanks,
Tom
