New colour for acknowledged problems?

[BirkirFreyr]

Would it be possible to implement a new type of marker-colour for hosts that have service in error state, but is acknowledged? So that we can see the difference between what is a current problem and what has been acknowledged.
Currently using NagVis for the map i'm hoping your module can take over for, but in NagVis the marker turns blue for problems hosts where all error/warning states have been acknowledged, and the users really want that kind of behaviour (doesn't have to be blue, just not the standard red/yellow).

If this is already possible, then a link to the documentation would be great (if it exists yet)

Sorry for the late feedback, but I was quite busy these days.

For now this feature is not implemented but I have it on my personal wish list and will try to ship it with the next release.
