If I have understood, you would like to change following symbols:

point gradient
line gradient
line slope

I thought, you have already changed at least some of these symbols
(see Jenny's map of Eislufthohle
http://cucc.survex.com/expo/plateau/76/76_final_col_small.png).
In any case, we should probably create BCRA symbol set in standard therion
distribution. We will try...
