"item-group" disable for Player Inventory

[Kalthor]

I createt for my Mod an own item-group with an item-subgroup. Now i want that this Group didn´t show up in the Player inventory only in the Assemblers.
Is this impossible and if not how could i make this ?

Sry for the bad English it isn´t my native language.

You have to add the item group to the player as a valid item group as you would with assembling machines.
