Different Types of Artillery?

[DedlySpyder]

So, I had an idea, but I think it would require something in the background to become moddable. Basically, to have something like the artillery turrets, but not within the same pool used for firing (so it would have a different targeting that it would only fire on, and the base turrets wouldn't fire at).

My assumption from looking at the prototypes for how artillery works are this:

• The artillery-targeting-remote places an "artillery-flare"
• An artillery-wagon-cannon (used for both the wagon and turret) within range fires on that flare

So my request based on that is to have different "types" of artillery, probably specified under the flare and the gun itself, if that is possible.
