Is it possible to buy the pack DIRECTLY, rather than playing with the time limit?

Some players have voluntarily calibrated the time limit to open their 2 (or 3) packs when they wake up, or at night before going to bed...

HOWEVER, if you want to open packs OUTSIDE this time limit, it just shifts your routine (because you just decrease the timer to open the next pack).

Is it possible to buy the pack DIRECTLY without affecting the time limit?
Thank you.
