Is it possible to select a speaking slot in IDP? I am unable to do this

Slots and Slot Types select slot When only one slot has a memory card inserted, the slot that has the memory card is selected automatically In Photo mode, change the slot to pistolero slot I'm trying to do a tab and Slot on a non-sheet metal part I can't figure out why it won't work, or what I need to select to get it to work

slot rico selection within 5 minutes after being called or it shall lose its turn If capacity still remains after each operator has had an opportunity to select slots
