[Therion] Two extended profiles for same survey

[Roger Schuster]

Hello cavers,

assume there are survey shots like this

0-1

1-2

1-3

1-4

(the numbers are the station names) forming a cross-shaped survey. I 
want to draw two extended profiles along the legs 0-1-2 (hiding stations 
3 and 4) and 3-1-4 (hiding stations 0 and 2). This means the station 
names required for the "extend hide" directives are mutually exclusive. 
Is it possible to work around this problem?

Thanks in advance!

Regards,

Roger
