Question: Defensive buildings multi-targeting

Hi all, so I have always felt that Aoe defensive buildings sometimes are not as usefull as they should be, I know there mods and cards that enhanced them, via making them have more hp, attack & range.

But I was wondering if would be posible for them to attack several targets, ex. An outpost to strike 2 to 4 different units, or a Fortress/ war hut to do the same.

To instead of making it a killer, to have some kind of “crowd control”, by attacking simoltanously several units nearby dealing the same amount of damage.

If so how? and what you think if this would be implemented? Comment please
