Enable/Disable Auto-optimize

There are actually two parts to this question:

1. Can I stop certain items from being equipped through the "Optimum" option in the equip screen?  For example, if a cursed object gives a defense of 100, can I make it so it will not auto-equip with the optimum feature?

2. I created a new set of beefed up Genji Gloves specifically for Leo/Cyan (not called Genji Gloves), but I need to make it so this item takes the player to the Equip screen when they equip the relic (just like the Gauntlet and Genji Glove).  Can I do this? The item in question uses a new relic slot and does not replace the old Genji Gloves or Gauntlet (hence the reason it does not take the player to the equip screen as it should).

Edit: I found a few threads in which people tried this, but the answers weren't very clear. If it might break something to do these things, I might just scrap the idea and skip this.
