Survex LRUD at a t-junction

So I've surveyed up to a T-junction (say station 2) and turned right and continued up to the end (station 5). Then headed back to the T-junction and continued surveying (first leg 2 -> 6) onwards to the end (station 8).

I've inputed the LRUD data for all points up to 8, not repeating station 2. However when displaying tubes in Aven it shows a new passage heading from station 5 to station 6! How do i stop this?!?

I've tried deleting LRUD data for 5 and/or 6, but it just moves where the passage starts/ends.

It's a bit of a pain to set up. You need to break it down into separate tubes.

The first would be for passage 1-2-3-4-5. Then you need a separate tube for 2-6-7-8.

Thanks Rhys. So i think i tried that (as per below method) but it doesn't seem to make any difference....

*data passage station left right up down
1 0.3 0.3 0.2 0.1
2 1.1 0.7 0.2 0.2
3 1.4 1.1 0.5 0.5
4 1.4 2.2 5 0.5
5 1 0.8 0.3 0
2 0.7 1.1 0.2 0.2
6 1.1 0 0.5 0.2
7 1.2 0.5 0.6 0.2
8 7 0.8 1.5 1.2

Any thoughts?
