Please clarify the context of the phrase "at once" used in this message. Does it mean "at once" as in [do this] "right away" or [do this] "immediately"? Or does it mean "once" (without the "at") as in "one time" [performance] only?

"At the same time", "in a single step". I've added some context to the /qqq.
