The original game has that, except there's only one arrow. Unless you have several pages of things on the ground, there's no need for more than one page. Even with all the things I've added to my mod, I don't get more than 3 pages of stuff on the ground with everything added just to take up space. I can get 4 pages if I deliberately equip all of the launchers with different ammo so they don't stack, but that's just absurd. The only way I can imagine using 4 or more pages is if you aren't using ground stacking, or if you have brought a ridiculously large variety of weapons to combat and you aren't reasonably going to equip or use them all.
