Feedback: Preferred Item Slots

I just played around with it, and I feel like there are improvements that can be made, I hope Gameplay is the right board since it affects gameplay.

1. Global: I did make a global Item Set with just where I want things, but it's a hassle to switch to it, unless there's a key to quickswitch between item sets in game it's unfortunate that I'll likely ignore my global item set with preferred item slots and just move them manually still since this feature is kind of neat. So maybe give us a global page where we choose items that will effect Default and Other Pages you make UNLESS you set them up on the specific page, then it would overwrite that global page.

2. Priority: As it is now, If you buy an activated item, then buy one that you would prefer to take over that item's slot, it won't. Long-winded explanation, below, I shuffle things a lot but in a methodical way for specific item combos.

(Examples: I normally start 2 off as the potion button, but once I get a cutlass/bork/gunblade, I personally prefer that in slot 2. This also occurs on a few champions like that go Seraph's/Zhonya's, I prefer them both to be on 1 unless I'm getting both, then move Seraph's over to 2. Why? I don't know. I can't fix my brain this late into the game. Siimiliar overlaps with me preferring both gargoyle locket and randuin's on 3, but move one of them(usually randuin's then locket to 4) if I ever get both in the game. Don't normally get all 3, but if Randuin's comes back into favor.. you never know... also with supports that want frostqueen/zhonya's

3. Thank you: I like this feature and will make it work, even if I have to make a bunch of item sets, much more than I was using cause I'm just happy leaving things on default and buying my items from there/searching for the ones that don't appear with most champions, since the default hubs pretty well into items you need... for most champions....
