[Therion] Syntax for vertical passages

Hello fellows, I've faced a problem when I started to use therion for the surveys we do. The matter is that when we survey a vertical passage (a well) we are used to take such sets of measurements: shot from-to, length(vertical) and 3-5 combinations of azimuth and distance. Ex. 1-2 5m. (210' - 1,2m)(0' - 4m)(75' - 3m)(160' - 0m) 210' stands for 210 degrees etc. And I cannot find out how using syntax of therion to note these measurements. Or should I change the way I do notes. Thanks for any ideas and advises. Vilius A. Speleoclub "Ænigma" www.speleo.lt
