How to you store a req pack in your inventory

I want to buy req packs for a req opening video but want to store them in my inventory rather than having them open right at once. How to you do this.

If you buy them through waypoint it might? That is only a guess. Also earlier today, my xbox froze once I bought a req pack and then when I started the game back up, it was in my inventory.

Sorry but not possible. At least to my knowledge.

Buy it through the xbox one smartglass app. It won’t open automatically if you do that.

Buy them from Halo Waypoint directly, after getting points. Keeps them saved, and when you open your game: PRESTO! Packs are here!

Through Waypoint, it does. Tried it before the game launched for Silver Packs, saved mine.
