Alien Ammo + GS

Why is there no buy button as with munitions for credits, or a dialog box with “yes” / “no” with additional devices, ensuring that one doesnt accidently spent gs on ammunitions?

There is a warning that pops up when you equip GS ammo that tells you what will happen if you use them. Though I agree GS ammo should be different from normal ammo and ALWAYS have a “would you like to buy more” pop up after battle.
