Feature request: Fire support modules that provide different ammunition types

[CreepPork]

Is your feature request related to a problem? Sometimes, you don't have the time to setup an actual unit, and a target module, and put them into the right range to provide fire support or accuracy is very important.

Solution you'd like: It would be nice to have an extra module for the mortar and the howitzer (two separate modules) to "virtually" drop the fire support rounds but leaving the original HE round modules intact. This still provides the opportunity to quickly drop the HE rounds, as before.

Imagine, you would want to smoke screen via mortars/howitzers a beach that is being landed by friendly forces. With these modules, you could that very quickly and simply. But suddenly you want a precise attack of cluster munitions from a howitzer. With these modules you could.

Alternatives you've considered: I'm not sure how to go around if the module is copy-pasted. If it was pasted then, in my opinion, it should retain the previous settings and still drop artillery.
