Creating a prop

[ed26105]

I am not getting something relative to fixtures vs props.  I have created a bell with CCB pixels.  I have two 50 pixel strings that I am going to layout on the bell to create vertical and horizontal rows, so that I can do magic things with the bell.  The problem is I can't figure out how to create this prop in visualizer.

I am willing to take the time to plot individual single bulbs, make them RGB and assign channels.  But the manual says a prop is a collection of fixtures.  I make a handful of fixtures, but each of them show up on the right had side as both fixture and prop.  In the create fixture box, the drop down for prop shows none, and only none.

How to I create the prop to add the 100 individual bulbs to in the visualizer?

Found the button to create prop.  Not sure why I never was able to see it before.
