I am trying to make a single part consisting of a spur gear and an extruded circular disk I have created, however when I add a spur gear from the toolbox, I have no "Configure component" options in the left hand column that allows me to easily select number of teeth and module etc. The only way I can get these options is if I right click on the toolbox part and select "Create part". But then it takes me to another screen and the disk disappears.

I simply want to be able to have the spur gear and disk in the same workspace or whatever you call it, just like I created a disk and spur gear manually without the toolbox, and without having to create an assembly.

Is there a way to do this?
