How do you view enemy unit attack ranges?

In most, if not all, SRPG or turn-based strategy games you can put your cursor over an enemy unit, and press a button to view their attack range. I know you can view their movement range, which helps for direct attack units, but I have to manually calculate ranged units.

So, how do you view an enemy unit's attack range? Assuming it's possible, but I can't imagine that probably the most comprehensive SRPG of all time doesn't have that feature.
