Thanks all, for the warm welcome, feedback, and rep!

Steel General: I knew there was a good reason for doing so, thanks for pointing it out!

Anomaly & Gandwarf: I've edited symbols before but never took the time to try to create them because it sounds complicated and I have a notorious tendency to gloss over manuals and tutorials.

ravells: The color palette is indeed atrocious which is why I usually modify my maps in Paint Shop. I am not sure what you mean by using mismatched symbols - I sometimes mix and match my symbols. I am sure I have fallen into many CC2 traps on earlier maps, but appreciating the maps displayed on this site and elsewhere has improved my technique. I'll submit an intro and another piece later.
