Suggestion Semi-random plots/random within subtype

[Fielran]

I'd really like to see an option to randomize plots in city plans while maintaining the same subtype, so a clothing store could be any clothing store and a mess hall could be any mess hall. This would be particularly nice on city plans where the designer added related clutter around the plot.

If this is implemented, it would be nice to have a "gate" subtype of martial plot, so plots with settlement entrances would only swap with each other.
