[Therion] Revisiting Breaking extended elevations on specific stations

[Tarquin Wilton-Jones]

Hi all,

I have a puzzle that comes from my old puzzle:
https://therion.speleo.sk/wiki/breakingextend

1   2 1    0   -10
2   3 1    0   -10
3   4 1    45  -10
4   5 1    45  -10
5   6 1    45  -10
6   7 1    90  -10
7   8 1.71 225  60
8   9 1    225  10
9  10 1    225  10
10  2 1.8  225 -32.2
7  11 1    90  -10

Imagine you want to break the loop at station 7, so that Therion shows
1-2-3-4-5-6-7-11 as a single line, then 2-10-9-8-7 as a branch off it.
The break should be at the end of the branch:
    10-9-8-7
   /
1-2-3-4-5-6-7-11

If you say "extend ignore 7" or "extend ignore 7 6" it will do this:
1-2-10-9-8-7-11
   \
    3-4-5-6-7
Breaks at the right station, but on the wrong branch.

You can do "extend ignore 8 7" to break at the wrong station on the
right branch. If you use "extend ignore 7 11" it ignores you, and breaks
at the natural point, leg 2-3.

Is it actually possible to break at station 7 along the 2-10-9-8-7 branch?

Cheers!
