Family table component menu manager single/all

Imagine having an assembly with patterned groups of bolts and nuts of different sizes. You want to include these components in the family table. The menu manager asks single or all. What does this mean? All components in the group? In the pattern? In the subassembly? In the main assembly? Does it make sense the menu manager even asks for this? In a pattern, the components are supposed to be the same right? Where can I see if CREO picks a single one or all of them? How can I change it from "single" to "all" and vice versa?
