How to hide a BOM Component where assembly type is NONE during Assemble activity

Hi Experts ,

I have requirement where i have 4 BOM component and for one of them the assembly type is NONE and rest have INV Type .

However during the "Assemble" activity in POD ,the  operator should not see the BOM component which has been set has NONE .

Is there a way to achieve this ?

My second question is how to automatically assign the current SFC as an inventory id for one of the BOM component .

Thanks
