How to make custom cabinet knob

[Anonymous]

It is fine to make custom-cabinet door in choosing "library and objects->save selection as->cabinet door" as well as the door handle, and door leaf.

Based on the method, I make some cabinet knob, and save as "library and objects->save selection as->knob". There was no choice for the custom knob in the cabinet element. (Fig. 1)

Anyone know, how to make custom cabinet knob? What are the custom knobs used for?

They are used only in the Kitchen Cabinets. Don't know why.
