This is slightly different from what I'd need. Maybe I should descirbe a 
more detailed example.

Given a board with 4 nets going from left to right, and a large obstacle 
in the middle accross the board from top-down. The obstacle could be a 
trace that has 2 smd 1206 resistors in series. At the end, I will use the 
resistors to make bridges for the horizontal 4 nets. There are multiple 
different ways I can end up doing this, recently I had two boards where I 
routed the obstacle first and I knew I would need to pass nets below 
the 1206 resistors but I didn't know which nets they would be. So I placed 
the resistors in a way that there was room on the sides and also drawn two 
thin traces. This latter operation was off-grid for my normal TT spacing, 
so I've drawn it once and copied to the other bridges.


Pinning down the rats is very similar, but there I'd need to know which 
nets I'd bridge under the resistors much earlier. It may be that it 
wouldn't be a problem to think in advance that way.



About the rest, thanks for the description of your method. I think the one 
describing tagging fits in I/2 on the summary?

For the rat pinning down, I'll introduce I/4.
