option to lock stable experience

Maybe it’s in the game but I haven’t reached it, or maybe other people don’t think it’s necessary/useful, but I would like to see an option to lock specific creatures from gaining experience at the stable (i.e. the rest get experience, so not the abandonment punishment- perhaps a modification to that though).

I am simply curious, because maybe your play style is different than mine; but why would this be option be useful.

Like I can see maybe a modification of stable groups for this to work, put them in a NoEXP group and that group is locked from gaining.
