I'm working on a shoe figure. I have it grouped, and I'm almost ready to try setting it up as a figure, but something comes to mind as I'm working on it. There is a buckle on the shoe strap that I would not like to have deform as the figure is made conforming, so my plan was to turn the buckle into a prop so that it remains its proper shape. 

Is it possible to set up the cr2 so that it loads the prop buckle at the same time it loads the shoe?

Yes, just save the figure to your library as a whole group. It will give you the option when you attempt to save the figure.

You could also leave the buckle as part of the shoe and just create morph targets to keep the buckle's shape, or use a weightmap. Saving it as a parented prop along with the shoe would be the easier/faster way, but the buckles will be left behind when the user deletes the shoe from the scene, unless they remember to check off the 'delete attached figures' option, which often is the case and can be annoying - like the eye lashes rex and roxie used to have.
