Ways to create a 3D target

[SgaragagghU 1]

I'm searching a way to create a 3D target on an objective (so i can view this 3d target from enywhere i'm am).

I can create a task and set the position where i want, it's working but there is a way to change the color of the "3D Arrow" or the description on the task?

Or anyway there is a way to do something like this in other way ?
