Queue unpack catas and bolts

[esu]

Hello !
I wonder why queuing catas/bolts doesn't work.
I tried to change queue to true in a replay, and that work ! so why doesn't it work in the game ?
I look for a mod that fix that, a way to enable it or maybe a reason why it doesn't work.
as a former starcraft player. i can't play a cata civ, since i always shift+unpack in the middle of nowhere, it's really annoying x')
that is the reason why i can't play a civ with catas :/

Discalaimer : maybe im not in the right section, maybe the problem is discussed somewhere else, sorry in that case, i didn't find anything about it with search field.
Thanks for reading and have nice day !
