Suggestion regarding artillery

[Imp]

Not if they are on map units.

Certain units I like to buy in groups, forget setting them up correctly.
Do this with FOOs, anti aircraft and sometimes ATGMs.
You can still cross attach them to a suitable Company.
Buy buying adjacent you can easily scroll through the units using N & P, helpful for FOOs.
Very helpfull for AA can find who can target the helo quickly.
Also AA and ATGM often have limited ammo so can cycle quickly to check.
