Hop-up Booster

I noticed that hop-up boosters can't be stored in the inventory.

It would be nice to hold at least one (or two) hop-up boosters until a compatible weapon is found.

I landed right on a hop-up booster in Somers University and couldn't store it. Its a minor hindrance to find a compatible weapon and then backtrack to find the hop-up booster.

I just no-filled pubs to make sure I couldn't store it before submitting this post. I ran through Stacks and Geyser and didn't find a hop-up booster. Maybe the hop-up booster should be purple rarity, instead of blue, since they're not a lot of them in the loot pool.

I also searched for the hop-up booster in the Firing Range and couldn't find one.
