Generally speaking, no.
1. The hex scale is 10 miles per, and by and large the heaviest guns were not pushed right up to the front. If you assume that a) your guns are a bit back, maybe 1/3 of their range, b) the enemy two hexes deep isn’t standing immediately on the hex border, then even the longest range artillery for WW2 will struggle to achieve anything meaningful, even with spotting assistance.
2. The combat engine is mostly concerned with dedicated assaults and defenses ranging from a few regiments to multi-corps operations, the actions of a battalion fire mission really aren’t the concern for the scale. The steady state shelling is mostly accounted for by increased attrition for units in contact, which is assumed to cover patrolling, small unit actions, your daily dose of shells, etc. - this isn’t small, as the “background hum” consumes tens of thousands of men every week.
3. Specific artillery units can attack from two hexes back in support of a fight - imagine pushing the guns up safely in your rear area for dedicated fire plans.
4. Counter battery is not, to the best of my knowledge, modeled beyond artillery shooting at artillery. Given there are at times 10M+ men fighting, the model is more concerned with “did the right number of guns die for an action” than it is with “make sure we account for acoustic ranging when that 122mm fires and a 105mm fires”
