Highlight controls with numbers that could be confused

Could the Highlight Adjacent Controls function also look for similar control codes, please?

British Orienteering rules say "control codes that could be easily confused are not to be used on control sites that are close to each other". It would be very useful if the Highlight could include controls where the codes are similar. My suggestion would be that 'similar' would be same except one digit where those digits are 1 and 7 or two of 0,6,8,9. It would be good to do this for controls within 200m of each other.

[At an event yesterday we had a formal protest about 112 and 172. The protest was rejected as they were 147m apart, but it would have been good to avoid it; an automated check would be extremely helpful]
