Unit Swapping?

[Tazz]

I'm doing some campaign editing rightnow, just the regular Korea campaigns. Having recently discovered the T-72 and T-80 tanks (yeah yeah I was rather late with that.. ), I would like to swap all the T-55 and T-62 tanks in my save0.cam file for T-72s and T-80s.

Is there any other way for doing this than deleting the T-55/T-62 units and adding new T-72/T-80 in TACEdit? This is taking me friggin AGES. There must be some sort of an 'equipment tag' or 'ID tag' that states what type of Battalion it is, T-62.. T-55 etc, so would a 'search & replace' be available for that, or perhaps is there a way to change an unit properity so it'll become a T-72/T-80 unit?
