Component Properties dialog box collapse configuration tree

Hello,

In the Component Properties dialog box, is there a way of collapsing everything in the configurations tree?

I have a part with several levels of derived configurations and hundreds of configurations at the lowest level. When selecting the configuration I want, I either have to scroll through all of them or collapse each tree item until I get to the one I want. Is there system setting to automatically display all of them collapsed, or a shortcut to collapse them all at once?

Thanks!
