Artillery Guard Mode, Is it technically possible? Options

[Jakato]

One thing that has always frustrated me in PvE is artillery. I'm not very good at micromanagement (I am super-duper forgetful) so I usually have two to four aircraft guarding critical areas. The idea is to be able to destroy AI attack forces so fast the artillery never gets a chance to wipe me out when my back is turned. Obviously this is more for when the AI is trying to take a supply dock from me than protecting my main base.

I wondered if it's possible for me to add a "Artillery" guard mode sort of like the "Aircraft" guard mode. I get there would need to be extra command buttons defined etc but I'm wondering if the AI can even filter out artillery units. I'm guessing the guard mode can filter units by their defined attributes (e.g. only attacking aircraft). However do all artillery units have a "artillery" attribute?

In a ideal world I could have lots if guard modes (infantry, AA etc) but that would not just be difficult in terms of scripting. Design issues would emerge too. You'd need a whole tab just for the guard modes, and SAGE seems to like having arbitrary limits so I bet I wouldn't be able to have enough guard buttons.
