My macro is pretty poor, and while playing the HotS campaign, I often find myself in cases where my larvae are simply idling. When I've built multiple hatcheries, with the campaign-specific 6-larvae cap, I often find myself with bunches of 12+ larvae.
Trying to turn these larvae into combat-ready units is irritating, as I need to press the appropriate button once per larvae. I know that in Starcraft the First, selected Larvae all morphed at once, resource permitting.
Is there a similar method to morph groups of larvae in Starcraft 2?
