I see a similar post but is from a year ago so I'm resubmitting this with a different approach (copy and paste from my reddit thread:
My suggestion is to add a button on the vehicles tab to automatically add to Queue trucks from an specific logistic network without having to go to the specific truck menu.
I don't think that programming wise is a hard thing to add maybe a simple thread searching for marked trucks or excavators would suffice for the cases where more than 10 trucks are selected at a time. In case that this results in a huge performance issue another solution is that the button put automatically in Q the x number of trucks possible in a 1 time process to not affect performance.
