Adding wounded units

[Black Fox]

Is it possible to have a unit on the campaign map replaced by a wounded version, for example:
I create a second version of that unit (this time with bandages, missing hats/helmets, ripped uniforms etc
and on the campaign map if the total unit strength is 230 (men) and it falls below 200 it is replaced with this second wounded version. So something along the lines of:
IF unit X = 200 insert unit X_wounded

thanks for any help on this
