Any way to vary range of detection in battle or on campaign map?

[Ichon]

Two different questions but I couldn't find reference to this by searching. I figure it is probably because both are hard coded but I'd just like to confirm that.

Are there any parameters to affect at what distance units can be detected on the battle map?

Same question for armies on the campaign map.

Battlemap - don't think you can change it, it's usually line of sight
Campaign - there are a couple of generic traits that increase viewing range. The effect is called "LineOfSight", I am not sure what the max value is.
