Requirement for Inventory Item

[MageFX]

Is it possible to set a "Requirements=" to an Inventory Item. Not as a cost but as an actually Requirement to progress up without the need to click to apply it?.

Example :

	Requirements = "player.hasItem && player.hasPermission('test.perm')"
            HandheldItem {
                SearchInventory = true
                ItemType = "minecraft:stone"
                UnsafeDamage = 0
                Count = 1
            }

In addition is it also not possible to have multiple HandheldItems as a cost for a action?
